[GIT PULL] AMD-TEE fix for v5.13

[Jens Wiklander]

Hello arm-soc maintainers,

Please pull this AMDTEE driver fix which adds reference counting to
loaded TAs which is needed for proper life cycle management of TAs.

Note that this isn't a usual Arm driver update. This targets AMD instead,
but is part of the TEE subsystem.

Thanks,
Jens
