Before merging I would like some feedback about adding
another product later, to ensure the compatibles above
are adequate? In particular:
- sequence of soc, cp, carrier compatibles
- name of som compatible

Draft for future bindings:
      - description:
          SolidRun CN9130 SoM based single-board computers
          with 1 external CP on the Carrier.
        items:
          - enum:
              - solidrun,cn9131-solidwan
          - const: marvell,cn9131
          - const: solidrun,cn9130-sr-som
          - const: marvell,cn9130
          - const: marvell,armada-ap807-quad
          - const: marvell,armada-ap807

      - description:
          SolidRun CN9132 COM-Express Type 7 based single-board computers
          with 2 external CPs on the COM.
        items:
          - enum:
              - solidrun,cn9132-clearfog
          - const: solidrun,cn9132-cex7
          - const: marvell,cn9132
          - const: marvell,cn9131
          - const: marvell,cn9130
          - const: marvell,armada-ap807-quad
          - const: marvell,armada-ap807
