arm64: dts: renesas: r9a09g011: Add PWC support

The RZ/V2M SoC contains an External Power Sequence Controller (PWC)
module. This module provides an external power supply on/off
sequence, on/off signal for the LPDDR4 core power supply, General
Purpose Outputs, and key input signals.

This patch adds PWC support to the SoC specific device tree.
