The pipestat fields affect reporting of all vblank-related interrupts, so we
have to reset them during the irq_handler, and while enabling vblank
interrupts. Otherwise, if a pipe status field had been set to non-zero
before enabling reporting, we would never see an interrupt again.
This patch adds i915_enable_pipestat and i915_disable_pipestat to abstract
out the steps needed to change the reported interrupts.
