Several (15) drivers in media/usb/gspca use IF_ENABLED(CONFIG_INPUT)
to decide if they should call input* interfaces, but those drivers
do not build successfully when CONFIG_INPUT=m and the gspca drivers
are builtin (=y).  Making USB_GSPCA depend on INPUT || INPUT=n
fixes the build dependencies and allows all of them to build
cleanly.

Fixes these build errors (selections, not all are listed):
