drm/i915: Defeature DRRS on LNL+
DRRS has been defeatured on LNL+. Adjust HAS_DOUBLE_BUFFERED_M_N()
to match.
Note that the M/N registers still appear to be double buffered under
the hood but the double buffer update point is now documented to be
just the last register write to the M/N registers, so it no longer
happens synchronously with the vblank/MSA transmission. We should
perhaps rename HAS_DOUBLE_BUFFERED_M_N() to more accurately reflect
reality, but couldn't come up with a decent name right now...
