Add DT bindings for the ROHM BD9571MWV-M PMIC. This PMIC has
the following features:
- multiple voltage monitors for 1V8, 2V5, 3V3 voltage rail
- one voltage regulator for DVFS
- two GPIOs

V2: - Drop the compatible = "regulator-fixed" from the binding example,
it should not be there.
- List the VD09 regulator
V3: Replace bd9571@30 with pmic@30
