perf/x86: Add Meteor Lake support
From PMU's perspective, Meteor Lake is similar to Alder Lake. Both are
hybrid platforms, with e-core and p-core.
The key differences include:
- The e-core supports 2 PDIST GP counters (GP0 & GP1)
- New MSRs for the Module Snoop Response Events on the e-core.
- New Data Source fields are introduced for the e-core.
- There are 8 GP counters for the e-core.
- The load latency AUX event is not required for the p-core anymore.
- Retire Latency (Support in a separate patch) for both cores.
Since most of the code in the intel_pmu_init() should be the same as
Alder Lake, to avoid code duplication, share the path with Alder Lake.
Add new specific functions of extra_regs, and get_event_constraints
to support the OCR events, Module Snoop Response Events and 2 PDIST
GP counters on e-core.
Add new MTL specific mem_attrs which drops the load latency AUX event.
The Data Source field is extended to 4:0, which can contains max 32
sources.
The Retire Latency is implemented with a separate patch.
