drm/i915/mtl: Re-use ADL-P's "DC off" power well 



As with ADL-P, MTL's "DC off" power well should be a dependency of the
PGC and PGD power wells, not the entire PG2 well.  In fact, the DC5/DC6
requirements between the two platforms are the same, so the Xe_LPD "DC
off" well definition can just be re-used for Xe_LPD+.
