[PATCH 01/33] drm/i915: Convert intel_vgt_(de)balloon to uncore

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

More removal of implicit dev_priv from using old mmio accessors.

Furthermore these calls really operate on ggtt so it logically makes sense
if they take it as parameter.
