Mahua is a derivative of the Glymur SoC and shares a significant
portion of its interconnect topology with Glymur. As such, this
series extends the existing Glymur interconnect driver to support
Mahua, reusing common definitions where possible and adding
SoC-specific configurations where necessary.

Glymur and Kaanapali are codenames of Qualcomm SoCs, not acronyms.

Mahua is a derivative of the Glymur SoC. Extend the
Glymur driver to support Mahua by:
1. Adding new node definitions for interconnects that differ from Glymur
(Config NoC, High-Speed Coherent NoC, PCIe West ANOC/Slave NoC).
2. Reusing existing Glymur definitions for identical NoCs.
3. Overriding the channel and buswidth, with Mahua specific values for
the differing NoCs

Now as all RPMh interconnect drivers were converted to using the dynamic
IDs, drop support for non-dynamic ID allocation.

Declaring link_nodes as a double-pointer results in a syntax sugar in
the interconnect driver to typecast the array. Change the type of
link_nodes field to the array to remove the need for the extra typecast.

Add driver for the Qualcomm interconnect buses found in glymur
based platforms. The topology consists of several NoCs that are
controlled by a remote processor that collects the aggregated
bandwidth for each master-slave pairs.
