drm/i915: Add new frontbuffer tracking interface to queue flush
We want to wait dma fences in dirtyfb ioctl. As we don't want to make
dirtyfb ioctl as blocking call we need to use
dma_fence_add_callback. Callback used for dma_fence_add_callback is
called from atomic context. Due to this we need to add a new
frontbuffer tracking interface to queue flush.
v3:
- Check schedule work success rather than work being pending
- Init flush work when frontbuffer struct is initialized
v2: Check if flush work is already pending
