[ALSA] hda-intel - Merge hda-codec module to a single module

Merge hda-codec module to a single hda-intel module since this is the
only user right now.  Although hda-codec stuff is designed to be used
universally from different controller drivers, currently only one
controller interface (and compatibles) are used.  So, let's merge them
to a single module to save memory.
