  firmware: arm_ffa: Treat missing FF-A feature on a platform as a probe miss (2026-05-27 10:14:23 +0100)

----------------------------------------------------------------
Arm FF-A + SMCCC updates for v7.2

1. The FF-A core is moved onto the driver model by reverting the earlier
   rootfs initcall change and registering the core as a platform driver with
   a synthetic arm-ffa platform device. Enumerated FF-A devices are now
   parented below the FF-A core device, and probing is deferred until pKVM
   has completed its FF-A proxy initialisation.

2. The platform-driver conversion is also adjusted so systems without FF-A
   support treat early unsupported transport/version discovery as a quiet
   probe miss rather than a failed matched probe.

3. The register-based partition discovery path now honors the descriptor
   size reported by FFA_PARTITION_INFO_GET_REGS. This keeps parsing aligned
   for newer FF-A descriptor layouts while still copying only the fields the
   driver understands.

4. Also included is an Arm SMCCC fix for the optional SOC_ID name call: the
   name query now uses the SMC64 function ID required for returning eight
   characters per register.
