[PATCH/RFC 4/9] firmware: arm_scmi: Add a flag for power-management clocks

Power management of on-SoC modules is typically handled through two
methods: module power control and module clock gating.  The former is
exposed as an SCMI power domain, the latter as an SCMI clock.

Add a flag to indicate if a clock is intended for power-management of a
hardware module.

As the SCMI clock protocol does not support advertizing power-management
clocks yet, this flag can only be set by a quirk.
