Chris Wilson f856f847b2 drm/i915: Just clear the mmiodebug before a register access
When we enable the per-register access mmiodebug, it is to detect which
access is illegal. Reporting on earlier untraced access outside of the
mmiodebug does not help debugging (as the suspicion is immediately put
upon the current register which is not at fault)!
