WildcatLake (WCL) is a variant of PantherLake (PTL) and shares the same
uncore PMU features with PTL. Therefore, directly reuse Pantherlake's
uncore PMU enabling code for WildcatLake.

Hi Peter,
Wildcat Lake is a variant of Panther Lake, it shares same PMU capabilities
with Panther Lake. Could you please review this small patch-set? If no
issue, could you please merge this patch-set? Thanks.
