regulator: s2mps11: Convert driver completely to use set_ramp_delay callback
Since now we have ramp_delay and ramp_disable as standard regulator constraints and DT part using it so this patch removes legacy part i.e. getting ramp_delayxx and ramp_enable from pdata since it can be passed as standard regulator constraints.
