[U-Boot] [PATCH 08/11] udoo_neo: Add Windows boot support for UDOO Neo

[Henry Beberman]

From: Henry Beberman <henry.beberman at microsoft.com>

This patch adds a new bootable configuration for Windows 10 IoT Core on
the i.MX6 SoloX UDOO Neo.

It also adds a new device tree sources file for imx6sx-udoo-neo.dts.
This is not required by Windows or UEFI but the build system requires a
device tree when building SPL with flat image tree support.
