These power wells should be enabled/disabled according to the following dependency tree (enable top to bottom, disable bottom to top): PG0 | --PG1-- / \ PGA --PG2-- / | \ PGB PGC PGD PWR_WELL_CTL follows the general ICL/TGL design and places PG A-D in the bits that would have been PG 6-9 under the old scheme. PWR_WELL_CTL_{DDI,AUX}'s bit indexing for DDI's A-C and TC1 is the same as TGL, but DDI-D is placed at index 7 (bits 14 & 15).
