Bug description:
[SRU Justification]
[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.
