drm/i915: Convert dev_priv->dev backpointers to dev_priv->drm

Since drm_i915_private is now a subclass of drm_device we do not need to
chase the drm_i915_private->dev backpointer and can instead simply
access drm_i915_private->drm directly.

struct drm_i915_private *d;
identifier i;

(
- d->dev->i
+ d->drm.i

- d->dev
+ &d->drm
)

and for good measure the dev_priv->dev backpointer was removed entirely.
