Arm SCMI driver updates for v6.11

The main addition this time is the support for platform to agent(p2a
also referred sometimes as notification or Rx) channel completion via
interrupt driven method. Currently, the OSPM agent clears or
acknowledge the receipt of the norification or delayed response by
updating the flags in the shared memory region which the platform is
expected to poll.

On some platforms that are completely interrupt driven, the OSPM
agent is expected to send a response message instead. This change
adds the support for the same.

Other changes include addition of a separate mailing list specific to
SCMI to allow open discussions about the interface itself in addition
to the kernel driver updates and support for system suspend via the
platform noification used on some systems.
