[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.
