soc: qcom: apr: Don't use reg for domain id
The reg property represents the address and size on the bus that a device lives, but for APR the parent is a rpmsg bus, which does not have numerical addresses. Simply defining #address/#size-cells to 1 and 0, respectively, to silence the compiler is not an appropriate solution. Replace the use of "reg" with an APR specific property.
