media: i2c: rdacm20: Fix format definition

The RDACM20 camera supports a single image format which is currently
listed as MEDIA_BUS_FMT_UYVY8_2X8. As the video stream is transmitted on
the GMSL serial bus, the 2X8 variant does not apply.

Fix the format by using MEDIA_BUS_FMT_UYVY8_1X16.

This fixes a runtime error which is now triggered as the MAX9286
deserializer implements .link_validate().
