perf/x86/intel: Add Crestmont PMU

Browse source

The Grand Ridge and Sierra Forest are successors to Snow Ridge. They
both have Crestmont core. From the core PMU's perspective, they are
similar to the e-core of MTL. The only difference is the LBR event
logging feature, which will be implemented in the following patches.

Create a non-hybrid PMU setup for Grand Ridge and Sierra Forest.
