Subject: [PATCH] media: Fix P010 tiled format description

There is only 31 bytes of space (without null character) for format
description. P010 tiled format description overflows that for 1
character and warning is generated when used. Fix that by changing Cb to
U and Cr to V, which is also consistent with some other descriptions.

Fixes: 3c8e19d3d3f9 ("media: Add P010 tiled format")
