From: Vladimir Lypak <vladimir.lypak@xxxxxxxxx>
Add driver for interconnect busses found in MSM8953 based platforms.
The topology consists of four NoCs that are partially controlled by a
RPM processor.
Note that one of NoCs (System NoC) has a counterpart (System NoC MM)
that is modelled as child device to avoid resource conflicts, since it
uses same MMIO space for configuration.
