[PATCH 05/10] drm/i915: dev_priv cleanup in bridge/bar/mmio init code

[Tvrtko Ursulin <tursulin@ursulin.net>]

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

dev_priv is more appropriate for these so converting saves
some lines of source.

v2: Commit message and keep the pdev local variable. (Joonas Lahtinen)
