Why don't you use a "reg" property with "#address-cells = <2>" and
"#size-cells = <1>", so you can store offset and mask there?

ePAPR v1.1 says:
"The unit-address must match the first address specified in the reg property
of the node. If the node has no reg property, the @ and unit-address must
be omitted ..."
So you cannot have the "@8.0" without a "reg" property.
