Thanks.  Any chance to work on / submit other changes for Tegra
HD-audio support?

As already mentioned, I think a cleaner way would be to write
hda_platform.c instead of hacking hda_intel.c with ifdefs.
Some code in hda_intel.c (e.g. bus ops and PCM callbacks) can be moved
out, either as a new helper module or just merging into snd-hda-codec
helper module, so that they can be used by both hda_intel.c and
hda_platform.c.

Ideally, we may rename hda_intel.c with hda_pci.c, but I'm afraid this
would bring too many regressions for module options.
