firmware: arm_ffa: Update the FF-A command list with v1.2 additions

Arm Firmware Framework for A-profile(FFA) v1.2 introduces register based
discovery mechanism and direct messaging extensions that enables to target
specific UUID within a partition.

Let us add all the newly supported FF-A function IDs in the spec.
Also update to the error values and associated handling.

Merge tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
"The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
samsung, imx, zynq and amlogic platoforms are fairly small maintenance
changes, either addressing minor mistakes or enabling additional
hardware.

The qualcomm platform changes add a number of features and are larger
than the other ones combined, introducing the use of linux/cleanup.h
across several drivers, adding support for Snapdragon X1E and other
SoCs in platform drivers, a new "protection domain mapper" driver, and
a "shared memory bridge" driver.

The cznic "turris omnia" router based on Marvell Armada gets a
platform driver that talks to the board specific microcontroller.

The reset and cache subsystems get a few minor updates to SoC specific
drivers, while the ff-a, scmi and optee firmware drivers get some code
refactoring and new features"

Merge tag 'ffa-updates-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers

Arm FF-A driver updates for v6.11

The main addition is the split of bus and driver into distinct modules
The FF-A bus module is initialized at subsys_initcall level when builtin.

FF-A drivers initialization is now changed to module_init level so that
pKVM ffa proxy is all setup and running in case pKVM hypervisor needs to
trap and handle FF-A calls.

One of the reason for not having this split from the beginning is the
need to workaround the FF-A v1.0 NULL UUID. The FF-A bus layer called
into FF-A driver and populated the device UUID if it matches with the
driver attempting to match. Moving the workaround away from the FF-A
bus layer to the FF-A core driver as a bus notifier will help to remove
the dependency.

Keep the FF-A driver core stack, together with any configured transport,
in a different module initialized as module_init level.

FF-A drivers initialization is now changed to module_init level.

firmware: arm_ffa: Move the FF-A v1.0 NULL UUID workaround to bus notifier

Currently FF-A bus ffa_device_match() handles the workaround for the
FF-A v1.0 devices which are not populated with UUID to match. The FF-A
bus layer calls into FF-A driver and populates the device UUID if it
matches with the driver attempting to match.

But this forces to have both FF-A bus and core driver to be bundled into
a single module. However, keep it as a single module adds problems for
the FF-A driver registrations and their initcall levels.

In preparation to split the FF-A bus and the core driver into distinct
modules, we need to move the workaround away from the FF-A bus layer.
We can add it into the FF-A core driver as a bus notifier.

In order to do so, we need to always match any driver with the device if
the UUID is NULL and then during the driver binding phase, we can populate
the UUID if it matches with the driver UUID table using the bus notifiers.
We also need to add a check for NULL UUID before calling the device/driver
probe as devices with NULL UUID is possible since we match all for that
case.
