Subject: [PATCH] drm/i915: Call io_schedule() whilst whilsting for the GPU

Since we are waiting upon IO completion, inform the kernel through use
of the io_schedule() call rather than the regular schedule(). This
should allow the kernel to make better decisions regarding scheduling
and power management.
