Recent mgb4 firmwares have support for setting a variable framerate
independent of the signal framerate. Add/fix (the mgb4 driver already did
promote V4L2_CAP_TIMEPERFRAME, but it didn't work) support for
V4L2_CAP_TIMEPERFRAME to the driver to enable this feature.
Additionally add support for the DV timings API (VIDIOC_G_DV_TIMINGS,
VIDIOC_ENUM_DV_TIMINGS, ...) for the outputs that was missing. The timings
info is required/used for implementing the V4L2_CAP_TIMEPERFRAME
functionality.

Recent mgb4 firmwares support YUV in addition to the RGB image format.
Enable YUV in the driver when the FW supports it.

Digiteq Automotive MGB4 is a modular frame grabber PCIe card for automotive
video interfaces. As for now, two modules - FPD-Link and GMSL - are
available and supported by the driver. The card has two inputs and two
outputs (FPD-Link only).
In addition to the video interfaces it also provides a trigger signal
interface and a MTD interface for FPGA firmware upload.
