mfd: adp5585: Drop useless return statement

In adp5585_reset_ev_parse(), when parsing the
adi,reset-pulse-width-us property, we were returning in case it was
found and valid. No point in doing that as we'll be returning anyways
after the exiting the property scope. And it could actually lead to bugs
if new properties happen to added after this one.
