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