  firmware: arm_scmi: Fix the clock protocol supported version (2024-01-22 10:01:17 +0000)

----------------------------------------------------------------
Arm SCMI fixes for v6.8

Few fixes addressing the below issues:

1. A spurious IRQ related to the late reply can get wrongly associated
   with the new enqueued request resulting in misinterpretation of data
   in shared memory. This race-condition can be detected by looking at
   the channel status bits which the platform must set to the channel
   free before triggering the completion IRQ. Adding a consistency check
   to validate such condition will fix the issue.
2. Incorrect use of asm-generic/bug.h instead of generic linux/bUg.h
3. xa_store() can't check for possible duplication insertion, use
   xa_insert() instead
4. Fix the SCMI clock protocol version in the v3.2 SCMI specification
5. Incorrect upgrade of highest supported clock protocol version from
   v2.0 to v3.0
