Subject: [PATCH v2] media: uvcvideo: Fix power line control for
 Shine-Optics Camera

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.

Bus 003 Device 002: ID 3277:009e Shine-Optics Integrated Camera
