hda: add eapd support to additional idt codecs
PATCH 1/1 hda: add eapd support to additional idt codecs
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).
