media: mgb4: Fixed signal frame rate limit handling
Change the default DV timings for the outputs to produce a better signal
less "crippled" by the frame rate limiting. While the individual values
are now different, the resulting signal still matches the same default
display as before.
Additionally fix the corner case when the frame rate limit is set to zero
causing a "divide by zero" kernel panic.

media: mgb4: Add support for V4L2_CAP_TIMEPERFRAME
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.
