imx: Add MYiR Tech MYS-6ULX support

Browse source 
MYS-6ULX is single board computer (SBC) comes with eMMC or NAND based
on imx6ULL SoC from NXP and provision for expansion board. This
commit adds support only for SBC with NAND.

CPU:   Freescale i.MX6ULL rev1.1 528 MHz (running at 396 MHz)
CPU:   Commercial temperature grade (0C to 95C) at 45C
Reset cause: WDOG
Model: MYiR i.MX6ULL MYS-6ULX Single Board Computer with NAND
Board: MYiR MYS-6ULX 6ULL Single Board Computer
DRAM:  256 MiB
NAND:  256 MiB
MMC:   FSL_SDHC: 0
In:    serial@2020000
Out:   serial@2020000
Err:   serial@2020000
Net:   FEC0

Working:
 - Eth0
 - MMC/SD
 - NAND
 - UART 1
 - USB host

How to use U-Boot on MYiR MYS-6ULX Single Board Computer
--------------------------------------------------------
- Configure and build U-Boot for MYS-6ULX iMX6ULL:
$ make mrproper
$ make myir_mys_6ulx_defconfig
$ make
This will generate SPL and u-boot-dtb.img images.
Boot from MMC/SD:
- The SPL and u-boot-dtb.img images need to be flashed into the micro SD card:
$ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
$ sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
- Boot mode settings:
Boot switch position: SW1 -> 0
SW2 -> 1
SW3 -> 0
SW4 -> 1
Boot from NAND:
- Boot the board using SD/MMC or Serial download and load the SPL into memory
either from SD/MMC or TFTP.
Default MTD layout is 512k(spl),1m(uboot),1m(uboot-dup),-(ubi)
Flash SPL to NAND from SD/MMC,
$ ext4load mmc 0:2 $loadaddr SPL
$ nand erase.part spl
$ nandbcb init $loadaddr 0x0 $filesize
Flash u-boot proper to NAND from SD/MMC,
$ ext4load mmc 0:2 $loadaddr u-boot-dtb.img
$ nand erase.part uboot
$ nand write $loadaddr uboot $filesize
- Boot mode settings:
Boot switch position: SW1 -> 1
SW2 -> 0
SW3 -> 0
SW4 -> 1
- Connect the Serial cable to UART0 and the PC for the console.
- Reset the board using and U-Boot should boot from NAND.
