[PATCH 3/3] arm64: dts: aspeed: Add syscon phandle to AST2700 ADC nodes

[Billy Tsai]

Point the ADC nodes at their own syscon1 so the driver can correctly
locate the reference-voltage trimming data on AST2700, where syscon0
and syscon1 share the same device-tree node name and would otherwise
resolve to the wrong SCU.
