This adds support for ESPRESSObin-Ultra from Globalscale.

Specifications are similar to the base ESPRESSObin board, with main
difference being being WAN port with PoE capability and 2 additional ethernet ports.

Full specifications:

1x Marvell 64 bit Dual Core ARM A53 Armada 3700 SOC clocked up to 1.2Ghz
1x Topaz 6341 Networking Switch
1GB DDR4
8GB eMMC
1x WAN with 30W POE
4x Gb LAN
1x RTC Clock and battery
1x DC Jack
1x USB 3.0 Type A
1x USB 2.0 Type A
1x SIM NanoSIM card Slot
1x Power Button
4x LED
1x Reset button
1x microUSB for UART
1x M.2 2280 slot for memory
1x 2x2 802.11ac Wi-Fi
1x MiniPCIE slot for Wi-Fi (PCIe interface)
