Subject: [PATCH] ARM: dts nuvoton: Add EDAC node

From: "William A. Kennington III" <wak@...gle.com>

We have the driver support code, now we just need to expose the device
node which can export the EDAC properties for the system memory
controller. Tested on real hardware to verify that error counters show
up.
