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)

v2: - updated compatible string - added 'u-boot,dm-pre-reloc' to spi0 and spi-flash nodes - updated board defconfig (properly with savedefconfig this time) - removed unused PCA driver from defconfig
