media: uapi: Use unsigned int values for assigning bits in u32 fields

Use unsigned int values annoted by "U" for u32 fields. While this is a
good practice, there doesn't appear to be a bug that this patch would fix.

The patch has been generated using the following command:

	perl -i -pe 's/\([0-9]+\K <</U <</g; s/\|\s*0\K\)/U\)/' \
		include/uapi/linux/media.h
