While DG2 supports DC5 and DC9, some of the tests in
fast-feedback blew up DG2 when the tests forced transition
from dc5->dc9 on suspend and dc9->dc5 on resume. Some local
experiments performed with Rodrigo on a RIL system  showed promising
results when dc5 was completely diabled and i915 took only dc9 paths.

Sending this so we can check the CI results to confirm the
findings from local testing which will hopefully help narrow
down the root cause of MMIO BAR lost issue
