Subject: pipeline: uvcvideo: Add color space support
Add support for color space to the uvcvideo pipeline handler. UVC
devices have a fixed color space per format, so only the validate()
function needs to be extended to retrieve the color space from the
kernel. There is no need to pass the value back to the driver in
configure().
