The BananaPi M4 Berry is a development board using the Allwinner H618
SoC. It comes with the following specs:
	- Allwinner H618 SoC (4 * Arm Cortex-A53 cores, 1MB L2 cache)
	- 2 GiB LPDDR4 DRAM
	- 8 GiB eMMC flash
	- AXP313a PMIC
	- Gigabit Ethernet, using RTL8211 PHY
	- RTL8821CU USB WiFi chip
	- HDMI port
	- 4 * USB 2.0 ports, via an on-board hub chip
	- microSD card slot
	- 3.5mm A/V port
	- power supply and USB-OTG via USB-C connector

Add a devicetree file describing the components that we already have
bindings for, that excludes audio and video at the moment.

Just drop above node. I get that it's for documenting purposes, but user need
to use DT overlay in any case.
