  firmware: arm_ffa: Split bus and driver into distinct modules (2024-05-29 23:23:25 +0100)

----------------------------------------------------------------
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.
