imx: Add PHYTEC phyBOARD-i.MX6UL-Segin

Browse Source 
Port for the PHYTEC phyBOARD-i.MX6UL-Segin single board computer. Based on
the PHYTEC phyCORE-i.MX6UL SOM (PCL063).

CPU:   Freescale i.MX6UL rev1.2 528 MHz (running at 396 MHz)
CPU:   Industrial temperature grade (-40C to 105C) at 44C
Reset cause: POR
Board: PHYTEC phyCORE-i.MX6UL
I2C:   ready
DRAM:  256 MiB
NAND:  512 MiB
MMC:   FSL_SDHC: 0
In:    serial
Out:   serial
Err:   serial
Net:   FEC0

Working:
 - Eth0
 - i2C
 - MMC/SD
 - NAND
 - UART (1 & 5)
 - USB (host & otg)

How to use U-Boot on PHYTEC phyBOARD-i.MX6UL-Segin
--------------------------------------------------
- Configure and build U-Boot for phyCORE-i.MX6UL:
$ make mrproper
$ make phycore_pcl063_defconfig
$ make
This will generate SPL and u-boot-dtb.img images.
- 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
- Jumper settings:
JP1: Open: Boot from NAND
Closed: Boot from SD/MMC1
- Connect the Serial cable to UART0 and the PC for the console.
- Insert the micro SD card in the board and power it up.
- U-Boot messages should come up.
