anx74xx: enable driver "release".

Browse Source 
TEST="make buildall" succeeds, "make runtests" passes for reef.

returning SUCCESS instead of UNIMPLEMENTED from .release() means the
pd_task() is allowed to reinitialize the TCPC when coming out of
PD_STATE_SUSPENDED or similar scenario.

TEST=verified anx3429 firmware update succeeds, USB port still usable
	for charging after update.
