ARM: dts: microchip: at91-sama7g5ek: Replace regulator-suspend-voltage with the valid property

[ Upstream commit e027b71762e84ee9d4ba9ad5401b956b9e83ed2a ]

By checking the pmic node with microchip,mcp16502.yaml#
'regulator-suspend-voltage' does not match any of the
regexes 'pinctrl-[0-9]+' from schema microchip,mcp16502.yaml#
which inherits regulator.yaml#. So replace regulator-suspend-voltage
with regulator-suspend-microvolt to avoid the inconsitency.
