dt-bindings: soc: renesas: Add RZ/V2M PWC
The Renesas RZ/V2M External Power Sequence Controller (PWC) IP
is capable of:
* external power supply on/off sequence generation
* on/off signal generation for the LPDDR4 core power supply (LPVDD)
* key input signals processing
* general-purpose output pins
Add the corresponding dt-bindings.
