interconnect: qcom: icc-rpmh: Support child NoC device probe
As per e39bf2972c6e ("interconnect: icc-rpm: Support child NoC device probe") also update the rpmh interconnect driver to support probing NoCs that are modelled as child devices of a different NoC. As the driver doesn't yet use the 'reg' property, no change is done for that.
