Shawn Guo e39bf2972c interconnect: icc-rpm: Support child NoC device probe ... As shown in downstream DT[1], the System NoC of QCM2290 is modelled using 4 fab/noc devices: sys_noc + qup_virt + mmnrt_virt + mmrt_virt. Among those 3 virtual devices, qup is owned by RPM and has no regmap resource, while mmnrt and mmrt are owned by AP and share the same regmap as sys_noc. So it's logical to represent these virtual devices as child nodes of sys_noc in DT, so that such configuration can be supported with a couple of changes on qnoc_probe(): - If there are child nodes, populate them. - If the device descriptor has .regmap_cfg but there is no IOMEM resource for the device, use parent's regmap.
