Subject: [PATCH v3] arm64: allwinner: h5: add support for NanoPi NEO Plus 2

	Add initial DT support for NanoPi NEO Plus 2 by FriendlyELEC
		Allwinner quad core H5 Cortex A53 with an ARM Mali-450MP GPU
		1 GB DDR3 RAM
		8GB eMMC flash (Samsung KLM8G1WEPD-B031)
		micro SD card slot
		Gigabit Ethernet (external RTL8211E-VB-CG chip)
		802.11 b/g/n WiFi, Bluetooth 4.0 (Ampak AP6212A module)
		2x USB 2.0 host ports & 2x USB via headers

    The DTS is based on OrangePi PC 2, sun50i-h5-orangepi-pc2
    Added dwmac-sun8i Gigabit Ethernet support based on
    Nano Pi Neo2 DT and the schematics.
