drm/i915: Sanitize the ADL-S power well definition

drm/i915: Sanitize the ADL-S power well definition

Instead of the skip_mask special casing of the ADL-S power well
descriptors, add a power well descriptor list for ADL-S as well reusing
the TGL descriptors, w/o the TC-cold power well. ADL-S doesn't have
TypeC PHYs, so a better way would be having ADL-S specific AUX
descriptors, but I left changing this for a follow-up.

This changes the ordering of the AUX and TC-cold vs. PW_4/5 power wells
on TGL and ADL-S, but this shouldn't make a difference (PW_4/5 don't
depend on the AUX/TC-cold power wells).
