mrc_cache: Move mrc_cache_stash_data to end of file

We need to pull update_mrc_cache into mrc_cache_stash_data, so moving
to end of the file to make sure update_mrc_cache is defined before.

BUG=b:150502246
BRANCH=None
TEST=Testing on a nami (x86) device:
     reboot from ec console.  Make sure memory training happens.
     reboot from ec console.  Make sure that we don't do training again.
