media: ti: j721e-csi2rx: add support for RGB formats

Browse source

Add support for RGB565, RGB888 and BGR888 media bus formats.

The pixel formats for these have a different byte-order than the MIPI
bus formats, given the SHIM IP [1] unpacks them into memory as follows:

MIPI RGB888 unpacks to:
BYTE3		BYTE2		BYTE1		BYTE0
00000000	RRRRRRRR	GGGGGGGG	BBBBBBBB

MIPI RGB565 unpacks to:
BIT 15-11	BIT 10-5	BIT 4-0
RRRRR		GGGGGG		BBBBB
