Arm SCMI firmware driver updates/fixes for v5.19

The main theme for most of the changes this time is around the addition
of the support for SCMI v3.1 specification changes. Though one of the main
addition in the specification is the powercap protocol, that is still
work in progress and this set includes all other changes bit and pieces
scattered all around the different parts of the specification. There are
few bugs discovered during the process and associated fixes and some
refactoring to simplify the addition of v3.1 support. It mainly includes
the support for extended names, few newly added notifications and async
command support.

Apart from v3.1 SCMI changes, OPTEE transport gets support for dynamic
shared memory.
