[PATCH v3 0/7] uvcvideo: Fix handling of power_line_frequency

[Ricardo Ribalda]

The uvc 1.5 standard recognizes 4 different values for this control, but we
were only using the first 3.

Also add a quirk for those devices that only support 50 and 60 Hz.

v3: Add more devices

v2: Thanks Laurent! 

Do not modify the behaviour of v1.1
