Subject: access/v4l2: add support for V4L2_PIX_FMT_ABGR32 and
V4L2_PIX_FMT_XBGR32
Fix broken v4l2 pixel format selection when the device supports/uses
the V4L2_PIX_FMT_ABGR32 or V4L2_PIX_FMT_XBGR32 pixel formats.
See the v4l2 documentation for the pixel formats details:
https://docs.kernel.org/userspace-api/media/v4l/pixfmt-rgb.html
