Remove protocol-specific versioning code and refactor all the protocols to use the new simplified centralized logic.

This is a sort of a peculiar quirk since it matches any platform and any firmware.

Add a check to verify if OEM types are supported before allowing any kind of OEM-specific get/set operation. Also add a check around all the new v3.2 clock features.

To implement the same let us stash the values of those permissions in the scmi_clock_info. They indicate if the operation is forbidden or not. If the CLOCK_GET_PERMISSIONS command is not supported, the default permissions are set to allow the operations, otherwise they will be set according to the response of CLOCK_GET_PERMISSIONS from the SCMI platform firmware.
