Zou Nan hai 8a9c3f5c34 drm/i915: remove loop in Ironlake interrupt handler 
commit c7c85101af upstream.

On Ironlake, there is an interrupt master control bit. With the bit
disabled before clearing IIR, we do not need to handle extra interrupt
in a loop. This patch removes the loop in Ironlake interrupt handler.
It fixed irq lost issue on some Ironlake platforms.
