[media] v4l: atmel-isi: Fix color component ordering

The ISI_CFG2.YCC_SWAP field controls color component ordering. The
datasheet lists the following orderings for the memory formats.

YCC_SWAP Byte 0 Byte 1 Byte 2 Byte 3
00: Default Cb(i) Y(i) Cr(i) Y(i+1)
01: Mode1 Cr(i) Y(i) Cb(i) Y(i+1)
10: Mode2 Y(i) Cb(i) Y(i+1) Cr(i)
11: Mode3 Y(i) Cr(i) Y(i+1) Cb(i)

This is based on a sensor format set to CbYCrY (UYVY). The driver
hardcodes the output memory format to YUYV, configure the ordering
accordingly.
