regulator: s5m8767: Pass descriptor instead of GPIO number
Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up from the device tree node for the
regulator.
This regulator supports passing platform data, but enable/sleep
regulators are looked up from the device tree exclusively, so
we can need not touch other files.
