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.

Thanks for the input As you mentioned we are going support only device tree.
