media: uvcvideo: Add support for P010 pixel format
Add support for the P010 (10-bit Y/UV 4:2:0) pixel format to the
uvcvideo driver. This format is exposed by USB capture devices such as
the Magewell USB Capture HDMI 4K Pro when capturing HDR10 content.
P010 stores 10-bit Y and interleaved UV samples in 16-bit little-endian
words, with data in the upper 10 bits and zeros in the lower 6 bits.
This requires 2 bytes per sample, so bytesperline is wWidth * 2.
V4L2_PIX_FMT_P010 was added to the V4L2 core in commit 5374d8fb75f3
("media: Add P010 video format").
Based on the community DKMS patch from awawa-dev/P010_for_V4L2.
