firmware: scmi: Add clock v3.2 CONFIG_SET support
SCMI v3.2 introduces a new clock CONFIG_SET message format that can
optionally carry also OEM specific configuration values beside the usual
clock enable/disable requests. Add support to use such new format when
talking to a v3.2 compliant SCMI platform.
Support existing enable/disable operations across different clock protocol
versions: this patch still does not add protocol operations to support the
new OEM specific optional configuration capabilities.
No functional change for the SCMI drivers users of the related enable and
disable clock operations.
[Marek: Remodel after Linux e49e314a2cf7 ("firmware: arm_scmi: Add clock v3.2 CONFIG_SET support")
Support both old < 2.1 and new >= 2.1 protocol versions.
Update commit message based on Linux one]
