[PATCH 2/2] arm: dts: xilinx: Add support for MYIR MYS-7Z020-V2 board

[Liu Yu]

Add device tree support for the MYIR MYS-7Z020-V2 board based on
the Xilinx Zynq-7000 XC7Z020 SoC.

The board supports:
- UART serial console
- MicroSD card interface
- Gigabit Ethernet
- QSPI NOR flash
- GPIO-based user LEDs and push-button
