Subject: [PATCH v3 0/5] Add QCS404 interconnect provider driver

Add drivers to support scaling of the on-chip interconnects on QCS404-based
platforms. Also add the necessary device-tree nodes, so that the driver for
each NoC can probe and register as interconnect-provider.

v3:
- Drop the patch introducing the qcom,qos DT property.
- Add two new patches to create an interconnect proxy device. This device is
  part of the RPM hardware and handles the communication of the bus bandwidth
  requests.
- Add a DT reg property and move the interconnect nodes under the "soc" node.

v2: https://lore.kernel.org/lkml/20190415104357.5305-1-georgi.djakov@linaro.org/
- Use the clk_bulk API. (Bjorn)
- Move the port IDs into the provider file. (Bjorn)
- Use ARRAY_SIZE in the macro to automagically count the num_links. (Bjorn)
- Improve code readability. (Bjorn)
- Add patch [4/4] introducing a qcom,qos DT property to represent the link to
  the MMIO QoS registers HW block.
