Actually paths and widgets are already decoupled from codec and moved
to card domain. Map/route is initialization time thing which still has
dependency to codec. I.e. snd_soc_dapm_add_route favors a widget from
a calling dapm context (codec).

This is due if there are machines with multiple codecs that are not
cross-connected but if they have widgets with a same name and I didn't
want to force them to use name prefixing and thus causing
userspace-kernel space breakage (kcontrol names changed) compared to
current implementation.
