CometLake is a platform from 2020, so I'd classified it as "legacy" and would
not apply this patch without a plausible justification in form of measurement
data.

Comet lake has been used with ACPI C-states for quite a long time, and switching
it to intel_idle now may cause unwelcome changes in user workloads.
