Currently i915 dirtyfb ioctl is not taking dma fences into
account. This works with features like FBC, PSR, DRRS because our gem
code is triggering flush again when rendering completes. We are
targeting in getting rid of frontbuffer tracking code: Flusing hook
from gem code will be removed as well.

This patch set is adding dma fence handling into i915 dirtyfb ioctl.

v4:
 - Move invalidate back being done before cb is added
v3:
 - Check frontbuffer bits before adding any fence fb
 - Invalidate only when adding fence cb succeeds
 - Check schedule work success rather than work being pending
 - Init flush work when frontbuffer struct is initialized
v2:
 - Clear fbc and psr busy bits on flip
 - Check if flush work is already pending
 - Use dma_resv_get_singleton
