thermal: introduce the Power Allocator governor

The power allocator governor is a thermal governor that controls system
and device power allocation to control temperature. Conceptually, the
implementation divides the sustainable power of a thermal zone among
all the heat sources in that zone.

This governor relies on "power actors", entities that represent heat
sources. They can report current and maximum power consumption and
can set a given maximum power consumption, usually via a cooling
device.

The governor uses a Proportional Integral Derivative (PID) controller
driven by the temperature of the thermal zone. The output of the
controller is a power budget that is then allocated to each power
actor that can have bearing on the temperature we are trying to
control. It decides how much power to give each cooling device based
on the performance they are requesting. The PID controller ensures
that the total power budget does not exceed the control temperature.

thermal: Add QPNP PMIC temperature alarm driver

Add support for the temperature alarm peripheral found inside
Qualcomm plug-and-play (QPNP) PMIC chips. The temperature alarm
peripheral outputs a pulse on an interrupt line whenever the
thermal over temperature stage value changes.

Register a thermal sensor. The temperature reported by this thermal
sensor device should reflect the actual PMIC die temperature if an
ADC is present on the given PMIC. If no ADC is present, then the
reported temperature should be estimated from the over temperature
stage value.

thermal: intel Quark SoC X1000 DTS thermal driver

In Intel Quark SoC X1000, there is one on-die digital temperature sensor(DTS).
The DTS offers both hot & critical trip points.

However, in current distribution of UEFI BIOS for Quark platform, only
critical trip point is configured to be 105 degree Celsius (based on Quark
SW ver1.0.1 and hot trip point is not used due to lack of IRQ.

There is no active cooling device for Quark SoC, so Quark SoC thermal
management logic expects Linux distro to orderly power-off when temperature
of the DTS exceeds the configured critical trip point.

Kernel param "polling_delay" in milliseconds is used to control the frequency
the DTS temperature is read by thermal framework. It defaults to 2-second.
To change it, use kernel boot param "intel_quark_dts_thermal.polling_delay=X".

User interacts with Quark SoC DTS thermal driver through sysfs via:
/sys/class/thermal/thermal_zone0/

For example:
- to read DTS temperature
$ cat temp
- to read critical trip point
$ cat trip_point_0_temp
- to read trip point type
$ cat trip_point_0_type
- to emulate temperature raise to test orderly shutdown by Linux distro
$ echo 105 > emul_temp
