imx6: Add support for Toradex Apalis family of CoMs
This patch adds support for the following computer on modules (CoM) from
Toradex[A]:
Apalis iMX6 Quad 2GB IT - i.MX 6Quad 800MHz, 2GB DDR3, 4GB eMMC
-40° to +85° C Temp
Apalis iMX6 Quad 1GB - i.MX 6Quad 1GHz, 1GB DDR3, 4GB eMMC
0° to +70° C Temp
Apalis iMX6 Dual 1GB IT - i.MX 6Dual 800MHz, 1GB DDR3, 4GB eMMC
-40° to +85° C Temp
Apalis iMX6 Dual 512MB - i.MX 6Dual 1GHz, 512MB DDR3, 4GB eMMC
0° to +70° C Temp
I've developed and tested it on Quad 2GB IT v1.1A and Dual 512MB v1.1A
CoMs, using Ixora[B] carrier board v1.0A, but it should hopefuly work on
Eval[C] board as well.

C. https://www.toradex.com/products/carrier-board/apalis-evaluation-board
Flashing/recovery instructions:
1. Download and compile imx_loader for OpenWrt from
https://github.com/ynezz/imx_loader
2. Enter recovery mode as desribed in
https://developer.toradex.com/knowledge-base/imx-recovery-mode
3. Connect board via USB to the host computer, check that it's connected
by lsusb:
15a2:0054 Freescale Semiconductor, Inc. i.MX 6Dual/6Quad SystemOnChip
in RecoveryMode
4. Copy following OpenWrt images to imx_loader directory:
SPL
u-boot.img
u-boot-with-spl.imx
openwrt-imx6-apalis-recovery.scr
openwrt-imx6-apalis-squashfs.combined.bin
5. Run imx_usb in imx_loader directory
