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.

[Stephan: Drop separate mm-snoc that exists downstream since it's
actually the same NoC as SNoC in hardware, add qos_offset for BIMC,
add ab_coeff for mm-snoc nodes and BIMC]
