The AGBBUSY# bit in INSTPM caught my eye while reading the code and
having the spec open at the same time. This series makes the code match
the spec, and also closes a potential race condition (which may or may
not be real, depending on how the hardware works).

drm/i915: Frob AGPBUSY# bit before enabling the vblank interrupt
drm/i915: Flip the sense of AGPBUSY_DIS bit
