regulator: core: Fix voltage change propagations to supply regulators
Some regulators support get_voltage and some support get_voltage_sel
operations. Do voltage change propagation only when the current
regulator has a minimum dropout voltage specified or if the current
regulator lacks both get_voltage and get_voltage_sel operations.
