dt-bindings: interconnect: Convert snoc-mm to a sub-node of snoc
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.
