ASoC: topology: add SND_SOC_DOBJ_GRAPH type for dapm routes

Add a new dobj type SND_SOC_DOBJ_GRAPH for dapm routes
and add snd_soc_dobj member to struct snd_soc_dapm_route.
This enables device drivers to save driver specific
data pertaining to dapm routes and also be able
to clean up the data when the driver module is unloaded.

Also, reorder the snd_soc_dobj_type types to align with
matching topology header types.
