Merge tag 'scmi-updates-5.17' of git://git./linux/kernel/git/sudeep.holla/linux into arm/late

Arm SCMI firmware interface updates for v5.17

Couple of main additions:
- Support for OPTEE based SCMI transport to enable using SCMI service
  provided by OPTEE on some platforms
- Support for atomic SCMI transports which enables few SCMI transactions
  to be completed in atomic context. This involves other refactoring work
  associated with it. It also marks SMC and OPTEE as atomic transport as
  the commands are completed once the return

Other changes involves some trace and log enhancements and a miscellaneous
bug fix.
