mx6sx: Add support for mx6sx udoo neo boards

Add support for mx6sx udoo neo boards. For more information about these
boards, please check:
http://www.udoo.org/udoo-neo

The U-Boot and kernel dts patches will be removed when we bump U-Boot
to 2017.01 and kernel to 4.10 version as they have already been sent
upstream.

+Date: Sun, 16 Oct 2016 16:44:23 +0200
+Subject: ARM: dts: imx6sx: Add UDOO Neo support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add initial device trees for UDOO Neo Basic, Extended and Full boards:
+* Serial console is enabled, other serial ports are prepared.
+* I2C based PMIC is enabled.
+* Ethernet is enabled for Basic and Full.
+* SDHC is enabled, with the SDIO_PWR GPIO modeled as a regulator.
+* Both user LEDs are enabled, with the orange one reserved for the M4
+  and with the SD card as default trigger for the red LED.
+
+The decision on a board compatible string is deferred to later.

+Subject: [PATCH] mx6sx: Add initial support for UDOO Neo Board
+
+UDOO Neo Board is a development board from Seco that has three models:
+ - UDOO Neo Basic
+ - UDOO Neo Basic Kick Starter
+ - UDOO Neo Extended
+ - UDOO Neo Full
+
+All versions are based on the i.MX6 SoloX processor.
+
+For more details about the UDOO Neo board, please refer to:
+http://www.udoo.org/udoo-neo/
+
+This work is based on a previous commit of Francesco Montefoschi
+<francesco.monte@gmail.com>:
+https://github.com/fmntf/u-boot/commit/877b71184a5105e708024f232d36aed574961844
+
+Only tested on the UDOO Neo Full board.
