snoc and snoc-mm in downstream use the same address space a mistake which we have carried over into upstream. In silicon terms snoc-mm has been tacked on to the original snoc which came from msm8916. Convert to a better description where snoc-mm is a sub-node of snoc, thus avoiding a mmio remap collision when using the RPM interconnect driver.
