dt-bindings: interconnect: document the RPMh Network-On-Chip interconnect in Mahua SoC

Document the RPMh Network-on-Chip (NoC) interconnect for the Qualcomm
Mahua platform.

Mahua is a derivative of the Glymur SoC. Many interconnect nodes are
identical and continue to use Glymur fallback compatibles. Mahua
introduces SoC-specific configurations and topologies for several
NoC blocks, including CNOC, HSCNOC, PCIe West ANoC/Slave NoCs.
This updates the existing Glymur yaml schema to include Mahua-specific
compatible strings, using two-cell "fallback" compatibles wherever
the hardware is identical with Glymur.
