usb: uvc: Enumerate valid values for color matching
[ Upstream commit e16cab9c1596e251761d2bfb5e1467950d616963 ]
The color matching descriptors defined in the UVC Specification
contain 3 fields with discrete numeric values representing particular
settings. Enumerate those values so that later code setting them can
be more readable.
