Add nodes for the main interconnect of the imx8m series chips.

These nodes are bound to by devfreq and interconnect drivers.

Add a platform driver for the i.MX8MM SoC describing bus topology.

Bandwidth adjustments is currently only supported on the DDRC and main
NOC. Scaling for the vpu/gpu/display NICs could be added in the future.

This adds support for i.MX SoC family to interconnect framework.

Platform drivers can describe the interconnect graph and several
adjustment knobs where icc node bandwidth is converted to a
DEV_PM_QOS_MIN_FREQUENCY request.

The interconnect provider is probed through the main NOC device and
other adjustable nodes on the same graph are found from a
fsl,scalable-nodes phandle array property.

There is no single device which can represent the imx interconnect.
Instead of adding a virtual one just make the main &noc act as the
global interconnect provider.

The imx interconnect provider driver will scale the NOC and DDRC based
on bandwidth request. More scalable nodes can be added in the future,
for example for audio/display/vpu/gpu NICs.

Add initial support for dynamic frequency switching on pieces of the imx
interconnect fabric.

All this driver does is set a clk rate based on an opp table, it does
not map register areas.

Add initial dt bindings for the interconnects inside i.MX chips.
Multiple external IPs are involved but SOC integration means the
software controllable interfaces are very similar.

Main NOC node acts as interconnect provider if #interconnect-cells is
present. Currently there is a single imx interconnect provider for the
whole SOC.

Other pieces of scalable interconnects can be present, each with their
own OPP table.

This uses our packaging instead of plain `make bindeb-pkg` so it can
easily be tested on devices.

We add the current topmost commit to the changelog and add +gitlabci1 to
the version number so it becomes easy to identify.

Somewhat based on what the kernel creates with `make deb-pkg` but
modified to make it more like a proper Debian package.

Can be built with:
