Subject: [PATCH v2 4/7] ARM: dts: microchip: at91-sama7g54_curiosity: Add reg_5v to supply PMIC nodes
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
