Arm SCMI driver updates for v6.11

Browse source 
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.
