xinglong.yang 189df98777 firmware: arm_scmi: Check beforehand if the perf domain set operations are allowed 
Certain SCMI performance domains may have restrictions on the set level
and/or limits operation. If the set level/limits are performed by an
agent who is not allowed to do so may get SCMI_ERR_SUPPORT. However,
since this information about the domain is already known to the
agent(OSPM here) obtained via PERF_DOMAIN_ATTRIBUTES, the agent(OSPM)
can avoid making PERF_LEVEL_SET and PERF_LIMITS_SET calls to the firmware.

Add those checks and return -ENOTSUPP to the caller without interacting
with the firmware based on the information collected during the domain
enumeration stage.
