The implementation uses AMU registers accessible as Fixed-feature Hardware (FFixedHW) for monitoring the performance. Non-secure SCMI fastchannels are used to communicate with LCP to set the desired performance. RD-Fremont platform does not support CPPC revision 1 and below. So update the _OSC method to let OSPM know about this fact.
