[PATCH v2 5/7] ARM: dts: microchip: at91-sama5d2_icp: Add reg_5v to supply PMIC nodes

From: Andrei Simion
Date: Mon Aug 12 2024 - 09:55:24 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
