Arm SCMI firmware driver updates/fixes for v5.19

The main theme for most of the changes this time is around the addition
of the support for SCMI v3.1 specification changes. Though one of the main
addition in the specification is the powercap protocol, that is still
work in progress and this set includes all other changes bit and pieces
scattered all around the different parts of the specification. There are
few bugs discovered during the process and associated fixes and some
refactoring to simplify the addition of v3.1 support. It mainly includes
the support for extended names, few newly added notifications and async
command support.

Apart from v3.1 SCMI changes, OPTEE transport gets support for dynamic
shared memory.

Arm FF-A firmware driver updates/fixes for v5.19

Couple of fixes to handle fragmented memory descriptors and incorrect
UUID parameter passed to ffa_partition_probe. Another fix deals with
the incorrect use of ffa_device's driver_data by the core driver.
Apart from these fixes, there is an addition of ffa_dev_get_drvdata helper

checked for NULL, causing the following smatch warnings:

Allow OMAP_GPMC to be built as a module.

When building this driver as a module, the symbol
'of_default_bus_match_table' will not be found as it is not being
exported.

The of_match_node() call is redundant anyways as
of_platform_default_populate() already takes care of matching with
'of_default_bus_match_table'. So get rid of that call. This will also
resolve the module build failure.

Add SCMI v3.1 voltage protocol support for asynchronous VOLTAGE_LEVEL_SET
command.

Note that, if a voltage domain is advertised to support the asynchronous
version of VOLTAGE_LEVEL_SET, the command will be issued asynchronously
unless explicitly requested to use the synchronous version by setting the
mode to SCMI_VOLTAGE_LEVEL_SET_SYNC when calling voltage_ops->level_set.

The SCMI regulator driver level_set invocation has been left unchanged
so that it will transparently use the asynchronous version if available.

Starting with SCMI v3.1, the PERFORMANCE_LIMITS_SET command allows a user
to request only one between max and min ranges to be changed, while leaving
the other untouched if set to zero in the request. Anyway SCMI v3.1 states
also explicitly that you cannot leave both of those unchanged (zeroed) when
issuing such command, so add a proper check for this condition.
