Add 3840x2160 as valid resolution for the webcam capture input and
adjust the webcam intervals accordingly.

we'd like to use the vivid webcam capture device with a 4k resolution. This
basically seems to do the trick, though, I'm not sure if there is a particular
system in choosing values for the 'intervals' array.
