[PATCH 2/2] drm/i915: Remove special case for power well 1/MISC_IO state verification

[Imre Deak]

The special casing to ignore these power wells while checking if their
HW and SW state matches can be removed now. The reason the HW enabled
state of these power wells was changing in the back of the driver is
actually a DMC FW bug.  The previous patch added a workaround for that
and so now the power well's is_enabled() hook should report the correct
state always.
