[PATCH 2/3] dt-bindings: arm: marvell: Add Sophos XGS 107w NPU

[Nicolo Giuliani via B4 Relay]

From: Nicolo Giuliani <nicolo.giuliani6 at studio.unibo.it>

The Sophos XGS 87/107 desktop firewalls combine an AMD x86 host with a
separate network processing unit (NPU). The NPU is a Marvell Armada CN9130
SoC with its own eMMC and SPI NOR flash, connected to the x86 host over
PCIe. It serves the front panel ports through a Marvell 88E6193X switch.

Document the compatible string of the NPU board, with the CN9130 SoC
compatibles as fallbacks.
