[Intel-gfx] [PATCH 2/4] drm/i915: No need to power up PG2 for GMBUS on BXT

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

GMBUS lives in PG1, so no need to power up PG2. We do want to prevent
the DMC from making a mess of things though, so add GMBUS to the DC off
power well.
