ASoC: soc-core: Increment codec and platform driver refcounts before probing

Commit f6c2ed5d "ASoC: Fix the device references to codec and platform drivers"
moved codec and platform driver refcount increments from soc_bind_dai_link
to more appropriate places.

Adjust a little them so that refcounts are incremented before executing the
driver probe functions.
