arm64: dts: marvell: Add device tree for uDPU board 



This adds initial support for micro-DPU (uDPU) board which is based on
Armada-3720 SoC.  micro-DPU is the single-port FTTdp distribution point
unit made by Methode Electronics which offers complete modularity with
replaceable SFP modules both for uplink and downlink (G.hn over
twisted-pair, G.hn over coax, 1G and 2.5G Ethernet over Cat-5e cable).

On-board features:
- 512 MiB DDR3
- 2 x 2.5G SFP via HSGMII SERDES interface to the A3720 SoC
- USB 2.0 Type-C connector
- 4GB eMMC
- ETSI TS 101548 reverse powering via twisted pair (RJ45) or coax (F Type)
