Subject: [PATCH v3 3/3] arm64: dts: rockchip: add rk3318 A95X Z2 board

The rk3318 A95X Z2 boards are sold as TV box.
No further documentation is given, but from the dts files
extracted it seems that the rk3318 processor is simulair
to the rk3328. This dts file contains only the basic nodes
that have support in the mainline kernel.

Features:

CPU: RK3318 Quad-Core Cortex-A53
GPU: Mali-450
RAM: 2/4GB DDR3
ROM: EMMC 16/32/64GB
HDMI: HDMI 2.0a for 4k@...z
Ethernet: 10/100M standard RJ-45
WiFi: 2.4G+5G WIFI, 802.11 b/g/n
Bluetooth: 4.0
1 x USB 3.0
1 x USB 2.0
1 x Micro SD card slot
1 x SPDIF
1 x AV
1 x DC IN
