Adding a lowest priority hook init function, guaranteed to run after
all other initialization is completed, which is a good time to take
the EC out of reset.
Also moving pin hold release into the same function.
BRANCH=none
BUG=chrome-os-partner:55797
TEST=verified proper reset pulse generated on reef
verified that reef, kevin and gru all boot up as expected
