perf/x86/intel: Add Crestmont PMU
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.
