Adds SCMI clock protocol support in the SCMI message drivers as
defined in SCMI specification v2.0 [1]. Not all the messages
defined in the specification are supported.

Embedded upon CFG_SCMI_MSG_CLOCK=y.

Platform can provide one of the plat_scmi_clock_*() handler for the
supported operations set/get state/rate and others.

scmi_msg_get_clock_handler() sanitizes the message_id value
against any speculative use of clock ID as a index since by
SCMI specification, IDs are indices.

SCMI resource in this implementation are dumped or inspired by the
SCP-firmware implementation [2] of the SCMI protocol, server side.
