imx: imx6ul: Add support for Kontron Electronics SL/BL i.MX6UL/ULL boards (N63xx/N64xx)

Browse source 
This adds support for i.MX6UL/ULL-based evaluation kits with SoMs by
Kontron Electronics GmbH.

Currently there are the following SoM flavors (SoM-Line):
  * N6310: SOM with i.MX6UL-2, 256MB RAM, 256MB SPI NAND
  * N6311: SOM with i.MX6UL-2, 512MB RAM, 512MB SPI NAND
  * N6411: SOM with i.MX6ULL, 512MB RAM, 512MB SPI NAND

And the according evaluation boards (Board-Line):
  * N6310-S: Baseboard with SOM N6310, eMMC, display (optional), ...
  * N6311-S: Baseboard with SOM N6311, eMMC, display (optional), ...
  * N6411-S: Baseboard with SOM N6411, eMMC, display (optional), ...

Currently U-Boot describes i.MX6UL and i.MX6ULL through separate config
options at compile-time. Though the differences are so minor, that for
the scope of these SoMs we just use a single defconfig that is compatible
with both SoCs.

Kontron Electronics SL i.MX6UL/ULL SoM
======================================
The Kontron SoM-Line i.MX6UL/ULL (N6x1x) by Kontron Electronics GmbH is a SoM module
with either an i.MX6UL or i.MX6ULL SoC, 256/512 MB DDR3 RAM, SPI NOR, SPI NAND and Ethernet PHY.
The matching evaluation boards (Board-Line) have two Ethernet ports, USB 2.0,
RGB, SD card, CAN, RS485, RS232 and much more.
Quick Start
-----------
- Build U-Boot
- Boot
Build U-Boot
^^^^^^^^^^^^
.. code-block:: bash
$ make kontron-sl-mx6ul_defconfig
$ make
Burn the flash.bin to SD card at an offset of 1 KiB:
.. code-block:: bash
$ dd if=flash.bin of=/dev/sd[x] bs=1K seek=1 conv=notrunc
Boot
^^^^
Put the SD card in the slot on the board and apply power.
Further Information
-------------------
The bootloader configuration is setup to be used with kernel FIT images. Legacy
images might not be working out of the box.
Please see https://docs.kontron-electronics.de for further vendor documentation.
