[SRU][D/OEM-OSP1-B][PATCH 00/19] Add perf support for Comet Lake/Ice Lake CPU

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/1848978

[Impact]
There is no complete perf support for Comet Lake CPU. For Ice Lake, some
changes has been included in v5.3, but still misses CPU IDs.

[Fix]
perf support for Comet Lake is based on previous works for Ice Lake, so
changes for both have to be backported.

[Test Case]
On platforms with Comet Lake/Ice Lake CPUs, one should find new
cstate_pkg events c{8,9,10}-residency appear in output of `perf list`
for use.

[Regression Potential]
Low. This backports perf support for previously incompletedly supported
cpu models.
