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.
