media: imx: utils: fix and simplify pixel format enumeration
Merge yuv_formats and rgb_formats into a single array. Always loop over
all entries, skipping those that do not match the requested search
criteria. This simplifies the code, lets us get rid of the manual
counting of array entries, and stops accidentally ignoring some non-mbus
RGB formats.
Before:
$ v4l2-ctl -d /dev/video14 --list-formats-out
ioctl: VIDIOC_ENUM_FMT
Type: Video Output
[0]: 'UYVY' (UYVY 4:2:2)
[1]: 'YUYV' (YUYV 4:2:2)
[2]: 'YU12' (Planar YUV 4:2:0)
[3]: 'YV12' (Planar YVU 4:2:0)
[4]: '422P' (Planar YUV 4:2:2)
[5]: 'NV12' (Y/CbCr 4:2:0)
[6]: 'NV16' (Y/CbCr 4:2:2)
[7]: 'RGBP' (16-bit RGB 5-6-5)
[8]: 'RGB3' (24-bit RGB 8-8-8)
[9]: 'BX24' (32-bit XRGB 8-8-8-8)
After:
$ v4l2-ctl -d /dev/video14 --list-formats-out
ioctl: VIDIOC_ENUM_FMT
Type: Video Output
[0]: 'UYVY' (UYVY 4:2:2)
[1]: 'YUYV' (YUYV 4:2:2)
[2]: 'YU12' (Planar YUV 4:2:0)
[3]: 'YV12' (Planar YVU 4:2:0)
[4]: '422P' (Planar YUV 4:2:2)
[5]: 'NV12' (Y/CbCr 4:2:0)
[6]: 'NV16' (Y/CbCr 4:2:2)
[7]: 'RGBP' (16-bit RGB 5-6-5)
[8]: 'RGB3' (24-bit RGB 8-8-8)
[9]: 'BGR3' (24-bit BGR 8-8-8)
[10]: 'BX24' (32-bit XRGB 8-8-8-8)
[11]: 'XR24' (32-bit BGRX 8-8-8-8)
[12]: 'RX24' (32-bit XBGR 8-8-8-8)
[13]: 'XB24' (32-bit RGBX 8-8-8-8)
