I am probably confused as what you are trying to do, but I would simply do.

git checkout master
git submodule update
... everything is master (svn branches/release)

git checkout develop
git submodule update
... everything is develop (svn trunk)

if your working trees or index is not clean, git may be cautious about 
letting you do this to save you from loosing data.
