[ALSA] Enable capture from line-in and CD on Revolution 5.1

Enable capture from line-in and CD on the Revolution 5.1 card.
This patch adds support for switching between the 5 input channels of
the AK5365 ADC and modifies the Revolution 5.1 driver to make use of
this facility.  Previously the capture channel was fixed to channel 0
(microphone on the Revolution 5.1 card).
