arm64: dts: rockchip: Add Bananapi R2 Pro 



This patch adds Devicetree for Bananapi R2 Pro based on RK3568.
Add uart/sd/emmc/i2c/rk809/tsadc nodes for basic function.
Gmac0 is directly connected to wan-port so usable without additional
driver.
On gmac1 there is a switch (rtl8367rb) connected which have not yet a
driver in mainline.

Patch also prepares nodes for GPIO header.
