media: i2c: adv7180: Use MEDIA_BUS_FMT_UYVY8_1X16 for CSI2 output

6by9 · popcornmix · commit 4f9944c95eb6 · 2024-03-05T13:55:40.000Z
CSI2 devices are meant to use the 1Xnn formats rather than 2Xnn
such as MEDIA_BUS_FMT_UYVY8_2X8.

For devices with ADV7180_FLAG_MIPI_CSI2 set, use
MEDIA_BUS_FMT_UYVY8_1X16.
