dt-bindings: iio: adc: xlnx,versal-sysmon: don't redefine reg type

Remove the $ref from the reg property that assigns a type to it. This
is a standard property with type of "address", so assigning a different
type causes a conflict and even causes the dtschema tool to crash when
running `make dtbs_check`.
