Pass dev_priv instead of dev to all feature macros (IS_, HAS_,
INTEL_, etc.). This has the side effect that a bunch of functions
now get dev_priv passed instead of dev.
The main use of kdev_to_drm_minor() was as an intermediate step
when extracting dev_priv, so make that helper do that bit too,
and rename it kdev_to_i915_dm() (to differentiate it from
kdev_to_i915(), which goes about this in a different, non-compatible,
way).
All calls to INTEL_INFO()->gen have been replaced with
INTEL_GEN().
v2: Rename kdev_to_i915_dm() to kdev_minor_to_i915() (Chris)
