Add device tree bindings for the Qualcomm MSM8974 interconnect providers
that support setting system bandwidth requirements between various
network-on-chip fabrics.

Rob: I included in the next patch at the top a rough diagram showing the
relationship between different buses. I wanted to include that diagram
here, however I didn't since I assume that this document will be
transformed into HTML. I've seen some of the text bindings in the IIO
subsystem have nice ASCII-art diagrams, such as
Documentation/devicetree/bindings/iio/dac/dpot-dac.txt. Do you have any
suggestions for how this can go in the YAML bindings? Prefix the line
with four spaces, similiar to what is done in markdown?

Changes since v1:
- Don't include all compatibles in the examples. Removed interconnect
  GPU client from example as well.
- Dual license header file: BSD or GPL 2.0
