Commit 4791bd7d6adc ("media: imx: Try colorimetry at both sink and
source pads") reworked the way that formats are set on the sink pad of
the CSI subdevice, and accidentally removed video field handling.
Well, let me restate the problem. This driver never did have correct
field handling (as you demonstrate in this patch, the driver never
set/propagated the field type to its source pad). So it's not accurate
to say the patch is a fix. A better description is that it adds
rudimentary field handling.

Restore it by defaulting to V4L2_FIELD_NONE if the field value isn't
supported, with the only two supported value being V4L2_FIELD_NONE and
V4L2_FIELD_ALTERNATE.
