ALC658 SPDIF input patch

[Stefan Macher <Stefan.Macher@web.de>]

Hi,

I have made a patch to get SPDIF input working with the Realtek ALC658. 
Realtek has changed the meaning of the Pin47 function selection bit (MX7A bit 
1 ) between ALC655 and ALC658.

ALC655: 0 -> external amplifier power down; 1 -> SPDIF IN
ALC658: 0 -> SPDIF IN; 1 -> external amplifier power down


Can please anybody include this into CVS.

Thanks,
Stefan
