firmware: arm_scmi: Add clock OEM config clock operations 

JIRA: https://issues.redhat.com/browse/RHEL-9668

commit 141b4fa0362569138653cf0165d92d48576db3fa

    firmware: arm_scmi: Add clock OEM config clock operations

    Expose a couple of new SCMI clock operations to get and set OEM specific
    clock configurations when talking to an SCMI v3.2 compliant.

    Issuing such requests against an SCMI platform server not supporting v3.2
    extension for OEM specific clock configurations will fail.
