media: adv748x-afe: Use 1X16 media bus code

Now that the adv748x CSI-2 transmitter driver validates the supported
formats, it is required for subdevices along the pipeline to produce
and consume the same media bus codes.

The adv748x analog front end driver use the 2X8 variant of the UYVY8
media bus code, while the CSI-2 transmitter use the 1X16 variant, which
is the correct one to use for the serial bus.

Make the adv748x afe use the 1X16 format variant to maintain the
pipeline validation correct.
