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.

From 76e691fc7653b85d390e58710e5c7db73ca49367 Mon Sep 17 00:00:00 2001
From: Andreas Färber <afaerber@suse.de>
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

MX6X Udoo Neo board
http://www.udoo.org/udoo-neo/
To build a minimal support for these boards:
$ make mx6sx_udoo_neo_defconfig
$ make
Buildroot prepares a bootable "sdcard.img" image in the output/images/
directory, ready to be dumped on an SD card:
dd if=output/images/sdcard.img of=/dev/<your-microsd-device>
For details about the medium image layout, see the definition in
board/udoo/neo/genimage.cfg.
