feat(stpmic1): add USB OTG regulators 

Add regulators boost, pwr_sw1 and pwr_sw2 regulators related to
USB OTG supply BOOST, SW_OTG and SWIN/SWOUT. These regulators are
needed since manipulated during the suspend/resume power sequence
as per FDT description for stm32mp15x-xxx boards from
STMicroelectronics.
