8321fc0113 ALSA: snd-atmel-ac97c: cleanup register definitions 
This patch will remove traces of channel B registers, since they are not
used by the AC97C driver. Channel B might be used for other purposes.

The driver also adds channel status bits TXEMPTY and OVRUN and a
AC97C_CH_MASK macro to ease clearing a channel settings.
