The 2X8 variants of MEDIA_BUS_FMT_YUYV8_2X8 does not apply to serial
busses.

Drop it and while at it beautify the formats declaration list a little
by putting the opening curly brace after the comment.

While at it, should we also switch this to MEDIA_BUS_FMT_UYVY8_1X16,
which is the canonical format for YUV422 8-bit on CSI-2 ?

Should I ?
I forgot why UYVY is preferred over YUYV.

Also this will break quite some scripts for many users :)
Should I rather add it instead ?

No problem for me in either cases

It's a convention, we picked UYVY for CSI-2 a long time ago. Sensor
drivers should match that convention.

We can also support the non-standard YUYV order if the sensor does as
well, so I don't mind having both options here. The important part is to
have UYVY.

The subject says imx8mp but the file modified is imx8mq.  I assume the
subject is a typo.

To my knowledge, the 8mp uses the same csis as the 8mm.
