drm/i915: add color key support v4
Add new ioctls for getting and setting the current destination color
key. This allows for simple overlay display control by matching a color
key value in the primary plane before blending the overlay on top.
v2: remove unnecessary mutex acquire/release around reg accesses
v3: add support for full color key management
v4: fix copy & paste bug in snb_get_colorkey
don't bother checking min/max values against docs as the docs are likely
wrong (how could we handle 10bpc surface formats?)
