  The Renesas RZ/V2M External Power Sequence Controller (PWC)
IP is a multi-function device, and it's 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.

v1->v2: I have dropped syscon, simple-mfd, regmap, offset, and the child nodes.
v2->v3: No change.

I need to move the dt-bindings document to a different location.
I'll send a v4 to fix this issue.

Thanks,
Fab
