Add perf core PMU support for Intel Goldmont CPU cores:
- The init code is based on Silvermont.
- There is a new cache event list, based on the Silvermont cache event list.
- Goldmont has 32 LBR entries. It also uses new LBRv6 format, which
report the cycle information using upper 16-bit of the LBR_TO.
- It's recommended to use CPU_CLK_UNHALTED.CORE_P + NPEBS for precise cycles.
For details, please refer to the latest SDM058:
