media: staging: rkisp1: cap: change RGB24 format to XBGR32

Browse source

According to the TRM [1], the YUV->RGB conversion outputs
RGB 888 format with 4 bytes, where the last byte is ignored,
using big endian representation:

|___X___|___R___|___G___|___B___|
31      24      16      8       0

Which matches format V4L2_PIX_FMT_XBGR32 in little endian
representation, so replace it accordingly.

"24 bit word". What it means is that 4 bytes are used with
24bit for the RGB and the last byte is ignored.
This matches format V4L2_PIX_FMT_XBGR32.
