Jarkko Nikula 1784061957 ASoC: omap: rx51: Report headset insertion instead of video out cable 
It is more usefull to report headset instead of video out cable in response
to jack insertion as this is more usual use-case and because now the headset
feature is supported. Automatic accessory detection is not possible at the
moment so most sensible static accessory type have to be used.
