[PATCH v2 05/25] drm/i915: remove the i915_dpio debugfs entry

Imre Deak

There are igt tools that can read/write the DPIO registers, so having a
debugfs entry for only some of those registers is somewhat arbitrary /
redundant. Remove it.

v2:
- instead of fixing the entry by taking a power domain reference around
the register accesses, remove the entry (Ville)
