ALSA: hda - Move some definitions to new hda_priv.h 



Later commits adding support for hda platform drivers will want to use
the same defines and structures. Put them in a place reachable by both
hda_intel and the new platform driver.

This is a mostly a direct copy with a few whitespace and comment
changes to make checkpatch happy.
