There's no need to do this at all if you're only supporting audio when
booting use device tree. If you intend for audio to work when booting
using a board file, then the previous patch needs a bunch of rework
to make some of the code conditional on device tree; the same structure
as tegra_wm8903.c uses.

Talking of which, in the previous patch, you can remove a number of
things from tegra_alc5632.c if you are only supporting device tree, like
the DAPM route map, since that's parsed from device tree now.
