I had patches to remove SND_JACK_LINEOUT and to add separate kcontrols, 
but I forgot them.

Mark Brown has a raised question if the jack is really not driven as a 
line output[1], but I never answered him (sorry for that!) I don't know 
if the hardware is capable, but I think we better to remove it for now 
since the codec driver does not handle it.

Mark, does it sound reasonable?
