[PATCH] hda: add eapd support to additional idt codecs

[PATCH] hda: add eapd support to additional idt codecs

[Matthew Ranostay]

[-- Attachment #1: Type: text/plain, Size: 237 bytes --]

Added support for EAPD on the 927x, and 9227-8 IDT HDA codecs.
Enabling EAPD powers the internal speaker amp otherwise there is no 
sound on systems with an internal amp.

Thanks, added to HG tree now (with slight modification to follow
the standard coding style).
