Add FourCCs for 10- and 12-bit red format with padding to 16 bits. This
is a temporary addition until the formats gets merged in the upstream
kernel.

The corresponding patch has been merged in drm-next. Kieran, could you
maybe update the commit message to mention the upstream commit ID ? We
could update all our kernel headers while at it, but we would have to
wait for v5.16-rc1.
