[PATCH] media: mgb4: Fix DV timings limits

[tumic]

From: Martin Tůma <martin.tuma@xxxxxxxxxxxxxxxxxxxxx>

Provide the real DV timings limits in VIDIOC_DV_TIMINGS_CAP. For the
outputs the pixelclock is limited by the CMT table <25000kHz, 2*94642kHz>,
for the inputs a slightly broader range is possible. The minimal
supported/tested resolution is 64px.
