[PATCH 3/6] ARM: dts: microchip: at91-sama7g54_curiosity: Add reg_5v to supply PMIC nodes

[Andrei Simion <andrei.simion@xxxxxxxxxxxxx>]

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.
