media: uvcvideo: Fix power line control for SunplusIT camera
[ Upstream commit 6180056b0e0c097dad5d1569dcd661eaf509ea43 ]
The device does not implement the power line frequency control
correctly. It is a UVC 1.5 device, but implements the control as a UVC
1.1 device.
Add the corresponding control mapping override.
