video: fsl-dcu-fb: implement wait for VSYNC ioctrltoradex_vf_4.0-next
Implement ioctrl FBIO_WAITFORVSYNC which allows user space to wait for
next VSYNC. The ioctrl waits until the next vertical synchronization
phase has begun.
This reintroduces interrupt handling which has been removed in a
earlier commit 85f663301364 ("video: fsl-dcu-fb: remove underrun
interrupt handling")
