drm/i915/bdw: Broadwell also has the "power down well"
Just like Haswell, but with the small twist that the panel fitter for pipe A is
now also in the always-on power well.
v2: Use the new HAS_POWER_WELL macro.
v3: Rebase on top of intel_using_power_well patches.
v4: This time actually update the PFIT check correctly so that the
pipe A pfit is in the always-on domain.
v5: Rebase on top of the VGA power domain addition.
v6: Rebase on top of the new power domain infrastructure. Also pimp the commit
message a bit while at it.
v7: Use IS_BROADWELL instead of IS_GEN8 (Ville).
