Arnd Bergmann b610c55bdf Arm SCMI firmware interface updates for v5.18

Few main additions include:
 - 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.
 - Support for polling mode in SCMI VirtIO transport in order to support
   atomic operations
 - Support for atomic clock operations based on availability of atomic
   capability in the underlying SCMI transport
 
 Other changes involves some trace and log enhancements and miscellaneous
 bug fixes.
