perf/x86/intel/rapl: Support Skylake RAPL domains

Add Skylake client support for RAPL domains. In addition to RAPL domains
in Broadwell clients, it has support for platform domain (aka PSys). The
PSys domain controls the entire SoC instead of just a CPU package. Unlike
package domain, PSys support requires more than just processor level
implementation. The other parts in the system need additional HW level
signaling, which OEMs need to support. When not supported, the energy
counter register in PSys domain returns 0.

Also corrected error in comment for GPU counter, which previously was
DRAM counter.
