Each platform has raw event encoding format which specifies the bit positions for different fields. The fields from event code gets translated into performance monitoring mode control register (MMCRx) settings. Patch add macros to extract individual fields from the event code. Add functions for sanity checks, since testcases currently are only supported in power9 and power10.
