Sylwester Nawrocki d26a6635b2 [media] v4l: Add AUTO option for the V4L2_CID_POWER_LINE_FREQUENCY control 
V4L2_CID_POWER_LINE_FREQUENCY control allows applications to instruct
a driver what is the power line frequency so an appropriate filter
can be used by the device to cancel flicker by compensating the light
intensity ripple. Currently in the menu we have entries for 50 Hz and
60 Hz and for entirely disabling the anti-flicker filter.
However some devices are capable of automatically detecting the
frequency, so add V4L2_CID_POWER_LINE_FREQUENCY_AUTO entry for them.
