PATCH 3/5 regulator: Modify ramp_delay value for s5m8767a

As s5m8767a is revisioned, ramp_delay register is changed. 5mV/uS, 10mV/uS, 25mV/uS, 50mV/uS, 100mV/uS ramp delay can be selected.

This is fine but I'll wait until the preceeding patch has appeared in an -rc before applying as there's a code dependency and the prior patch is a bugfix which I'll send to Linus for 3.5.
