arm64: dts: rockchip: Add RK3562 evb2 devicetree 



DRAM: DDR4
Storage: eMMC
PMIC: RK809
Audio: Headphone and speaker
Interface:
- USB3.0 HOST
- USB2.0 HOST
- PCIe x4 slot(pcie2x1 available)
- SD card slot
- GMAC
- debug UART0

NOTE: the USB3.0 and the PCIe reuse the comboPHY, so the USB3.0 work in
USB2 only mode.
