[alsa-devel] [PATCH 03/11] ALSA: bebob: preparation for replacing string literals by normalized representation for model-dependent structures

Previous commit adds a enumerator as a normalized representation of
clock source, while model-dependent structures still use string literals
for this purpose.
This commit is a preparation for replacement.
