[Intel-gfx] [PATCH v6 04/24] drm/i915/dg1: Add DG1 power wells

From: Uma Shankar <uma.shankar at intel.com>
Most of TGL power wells are re-used for DG1. However, AUDIO Power
Domain is moved from PG3 to PG0. Handle the change and initialize
power wells with the new power well structure.
Some of the Audio Streaming logic still remains in PW3 so still
it needs to be enabled.
DDIA, DDIB, TC1 and TC2 are the active ports on DG1.
