This patch adds snd_soc_of_parse_audio_routing() to get dapm routes via Device Tree. Because snd_soc_of_parse_audio_routing() overrides dpam_routes, we use snd_soc_dapm_add_routes() to append the original build-in DPCM routes instead of linking them to dpam_routes directly.

It seems better to make the helper function play nicely with existing DAPM routes in the card rather than have to rearrange things like this. How about having it just record that it should parse the given property when the table in the card is being handleed rather than overwrite that?
