thermal: intel: Remove explicit user_space governor selection

Currently some user space programs like Linux thermald needs to register
to get notifications from both thermal user space governor and also
Thermal netlink. This is required as some messages like HFI (Hardware
Feedback Notifications) requires Thermal netlink.

This results in additional processing in kernel and user space to process
both notifications. The cost of using user space governor using
kobject_uevent is much higher as this is also used by other user space
daemons like udev daemon.

Do not select user_space thermal governor by default. If it is present
user space programs can always use this governor by writing to
"policy" attribute.

Instead from the kernel select THERMAL_NETLINK. Trip temperature
violation can be received by user space programs via thermal netlink
events:
THERMAL_GENL_EVENT_TZ_TRIP_UP
THERMAL_GENL_EVENT_TZ_TRIP_DOWN

Merge tag 'acpi-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.

Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.

Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)

In addition to that, there are the usual bunch of fixes and cleanups.

Specifics:

- Add CSI-2 and DisCo for Imaging support to the ACPI device
enumeration code (Sakari Ailus, Rafael J. Wysocki)

- Adjust the cpufreq thermal reduction algorithm in the ACPI
processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
Bergmann)

- Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)

- Switch over ACPI to using a threaded interrupt handler for the SCI
(Rafael J. Wysocki)

- Allow ACPI Notify () handlers to run on all CPUs and clean up the
ACPI interface for deferred events processing (Rafael J. Wysocki)

- Switch over the ACPI EC driver to using a threaded handler for the
dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)

- Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
to keep local interrupts on (Rafael J. Wysocki)

- Adjust the USB4 _OSC handshake to correctly handle cases in which
certain types of OS control are denied by the platform (Mika
Westerberg)

- Correct and clean up the generic function for parsing ACPI
data-only tables with array structure (Yuntao Wang)

- Modify acpi_dev_uid_match() to support different types of its
second argument and adjust its users accordingly (Raag Jadav)

- Clean up code related to acpi_evaluate_reference() and ACPI device
lists (Rafael J. Wysocki)

- Use generic ACPI helpers for evaluating trip point temperature
objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
Bergmann)

- Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
zone driver (Jeff Brasen)

- Modify the ACPI LPIT table handling code to avoid u32
multiplication overflows in state residency computations (Nikita
Kiryushin)

- Drop an unused helper function from the ACPI backlight (video)
driver and add a clarifying comment to it (Hans de Goede)

- Update the ACPI backlight driver to avoid using uninitialized
memory in some cases (Nikita Kiryushin)

- Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
Qiu)

- Add support for vendor-defined error types to the ACPI APEI error
injection code (Avadhut Naik)

- Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
memory failure events, so they are handled differently from the
asynchronous ones (Shuai Xue)

- Fix NULL pointer dereference check in the ACPI extlog driver
(Prarit Bhargava)

- Adjust the ACPI extlog driver to clear the Extended Error Log
status when RAS_CEC handled the error (Tony Luck)

- Add IRQ override quirks for some Infinity laptops and for TongFang
GMxXGxx (David McFarland, Hans de Goede)

- Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
not the same as one of the real pxm values (Yuntao Wang)

- Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
driver so as to prevent miscalculation of the values in the clock
divider (Andy Shevchenko)

- Adjust comments in the ACPI watchdog driver to prevent kernel-doc
from complaining during documentation builds (Randy Dunlap)

- Make the ACPI button driver send wakeup key events to user space in
addition to power button events on systems that can be woken up by
the power button (Ken Xue)

- Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
structure field (Dmitry Antipov)"

thermal: ACPI: Move the ACPI thermal library to drivers/acpi/

The ACPI thermal library contains functions that can be used to
retrieve trip point temperature values through the platform firmware
for various types of trip points. Each of these functions basically
evaluates a specific ACPI object, checks if the value produced by it
is reasonable and returns it (or THERMAL_TEMP_INVALID if anything
fails).

It made sense to hold it in drivers/thermal/ so long as it was only used
by the code in that directory, but since it is also going to be used by
the ACPI thermal driver located in drivers/acpi/, move it to the latter
in order to keep the code related to evaluating ACPI objects defined in
the specification proper together.

No intentional functional impact.
