vc/google/chromeos/ec: remove EC hibernate in cr50 update path

Browse Source 
More platforms are not able to hibernate under certain circumstances,
such as when AC is plugged. This original path was conservatively put in
to prevent potential damage when cr50-update-caused asynchronous resets
occur.  Julius' compelling argument that async resets from recovery mode
requests should have enough coverage of the design over the course of
project development. Remove the hibernate path and assume all is well
going forward.
