interconnect patches for 5.4

Here are the interconnect driver updates for the 5.4-rc1 merge window.

- New feature is the path tagging support that helps with grouping and
aggregating the bandwidth requests into separate buckets based on a tag.
- The first user of the path tagging is the Qualcomm sdm845 driver that
now implements support for wake/sleep sets. This allows consumer drivers
to express their bandwidth needs for the different CPU power states.
- New interconnect driver for the qcs404 platforms and a driver that
communicates bandwidth requests with remote processor over shared memory.
- Cleanups and fixes.

+Qualcomm QCS404 Network-On-Chip interconnect driver binding
+-----------------------------------------------------------
+
+Required properties :
+- compatible : shall contain only one of the following:
+			"qcom,qcs404-bimc"
+			"qcom,qcs404-pcnoc"
+			"qcom,qcs404-snoc"
+- #interconnect-cells : should contain 1
+
+reg : specifies the physical base address and size of registers
+clocks : list of phandles and specifiers to all interconnect bus clocks
+clock-names : clock names should include both "bus" and "bus_a"
+
+Example:
+
+soc {
