[RFC PATCH 6/9] ARM: dts: sun8i: add DTS file for Banana Pi M2 Ultra

[Icenowy Zheng <icenowy-ymACFijhrKM@public.gmane.org>]

Banana Pi M2 Ultra is a new board by Sinovoip (BPi), with R40 SoC,
AXP221 PMIC, 2GiB DRAM, 8GiB eMMC, a 40-pin RPi-like GPIO connector, a
HDMI connector, a SATA connector (native in SoC) as well as its power
supply, a Headphone jack, two USB ports, a 1000Mbps Ethernet port
(with RTL8211E PHY), a MicroSD slot, a battery connector, a DSI
connector and a CSI connector.

Add support for the board.
