V4L/DVB (3533): Add WSS (wide screen signalling) module parameters
Add wss_cfg_4_3 and wss_cfg_16_9 configuration options.
Firmware 2623 or later required.
Both parameters are bit masks:
- bit 15: disable WSS
- bit 14: send short WSS burst, then turn off WSS
- bit 13..0: WSS bits as specified by the standard
These parameters are useful if you own a broken tv set which
does not handle wss correctly.
Default settings:
- wss_cfg_4_3: 0x4008
- wss_cfg_16_9: 0x0007
These should work with most devices.
