[PATCH v2 7/7] ARM: dts: microchip: sama5d29_curiosity: Add reg_5v to supply PMIC nodes
From: Andrei Simion
Date: Mon Aug 12 2024 - 09:56:18 EST
Align with the datasheet by adding regulator-5v which
supplies each node from the regulator using phandle to
regulator-5v through pvin[1-4]-supply and lvin-supply.

v1 -> v2:
- drop (lvin|pvin[1-4])-supply from each regulators sub-node
- add lvin-supply, pvin[1-4]-supply to PMIC node
