[ALSA] soc - DAPM - Bulk route registration
ASoC codecs and machine drivers that use DAPM routes all cut'n'paste a loop iterating over a null terminated array of routes. Factor out this into a bulk registration function, improving the error reporting for most users, and deprecate the old API to help out of tree users pick up the changes.
