interconnect: qcom: Add MSM8909 interconnect provider driver Add driver for interconnect busses found in MSM8909 based platforms. The topology consists of three NoCs that are partially controlled by a RPM processor. In the downstream/vendor kernel from Qualcomm there is an additional "mm-snoc". However, it actually ends up using the same RPM "snoc_clk" as the normal "snoc". It looks like this is actually the same NoC in hardware and the "mm-snoc" was only defined to assign a different "qcom,util-fact" to increase bandwidth requests by a static margin. In mainline we can represent this by assigning the equivalent "ab_coeff" to all the nodes that are part of "mm-snoc" downstream.
