Subject: [PATCH 2/2] ARM: dts: zynq: Add linux,stdout-path and stdout-path

parallella - Use reference instead of hardcoded path
             (linux,stdout-path)

stdout-path is used by bootloader to identify console.

Signed-off-by: Michal Simek <michal.simek@...inx.com>
---

U-Boot driver model requires stdout-path.
