Booting tip-of-tree on msm8939 we find the following error caused by our
modelling of snoc and snoc_mm as peer devices with the same address space.
[ 1.212340] qnoc-msm8939 580000.interconnect_mm: can't request region for resource [mem 0x00580000-0x0059407f]
[ 1.212391] qnoc-msm8939 580000.interconnect_mm: Cannot ioremap interconnect bus resource
[ 1.221524] qnoc-msm8939: probe of 580000.interconnect_mm failed with error -16
Declaring snoc_mm as a child device of snoc mitigates the fault and is
consistent with a similar extant implementation in qcm2290.
