[RESEND] ARM: imx: mx6ull: Add iMX6ULL VisionSOM SoM and EVK

From: Arkadiusz Karas <arkadiusz.karas at somlabs.com>

Add iMX6ULL VisionSOM SoM and VisionCB-RT-STD evaluation board support.
The SoM has an iMX6ULL, 512 MiB of DRAM and microSD slot. The carrier
board has Ethernet, USB host port, USB OTG port.

NOTE: There are other variants and options of the VisionSOM available:
      - iMX6UL instead of iMX6ULL
      - NAND can be populated (optional, easy to add support for)
      - eMMC can be populated (optional, easy to add support for)

Patch was already applied to u-boot-imx, -master. I could not find it in
patchwork, that's the reason you did not get an e-mail of confirmation.
