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)
Tested on a imx6q-sabresd.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
