drm/i915: Clean up M/N register defines
Use REG_GENMASK() & co. for the M/N register values. There are
also a lot of weird unused defines (eg. *_OFFSET) we can just
throw out.
Also let's mask out the unused bits during readout for good
measure. Previously we only masked out the TU_SIZE from one
of the registers, which was a bit too inconsistent for my
taste.
v2: Mention the readout masking in the commit msg (Jani)
Deal wth gvt
