V4L/DVB: uvcvideo: Power line frequency control doesn't support GET_MIN/MAX/RES

Issuing a GET_MIN request on the power line frequency control times out
on at least the Apple iSight. As the UVC specification doesn't list
GET_MIN/MAX/RES as supported on that control, remove them from the
uvc_ctrls array.
