[34/54] arm64: dts: renesas: salvator-common: Add BD9571 PMIC

Commit Message

From: Geert Uytterhoeven <[e-mail]>

Add a device node for the ROHM BD9571MWV PMIC.

This was based on the example in the DT binding documentation, but using
IRQ0 instead of a GPIO interrupt, as that matches the schematics, and
because INTC-EX is a simpler block.
