v3:
- remove always-on from regulators that don't have on/off control
- place 'enable-active-high' righ tafter gpio prop in regulators
- remove unnecessary newline
- add newlines between properties and child node
- add newlines between child nodes
- remove unnecessary newline between properties
- add reviewed-by

v2:
- add missing GSC #address-cells and #size-cells
- use common node name for SPI FLASH and drop mb85rs4mt compatible
- add missing pinctrl-names to PMIC
- add rohm,reset-snvs-powered to PMIC
- add 32.768 kHz clock to PMIC
