board: toradex: add verdin imx8m plus support

This adds initial support for the Toradex Verdin iMX8M Plus Quad 4GB WB
IT V1.0B module. They are strapped to boot from eFuses which are factory
fused to properly boot from their on-module eMMC. U-Boot supports
booting from the on-module eMMC only, SDP support is disabled for now
due to missing i.MX 8M Plus USB support.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet both on-module eQoS and FEC (requires PHY on carrier board)
- GPIOs
- I2C

Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper

ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.

+Verdin iMX8M Plus Module
+========================
+
+Quick Start
+-----------
+
+- Build the ARM trusted firmware binary
+- Get the DDR firmware
+- Build U-Boot
+- Flash to eMMC
+- Boot
+
+Get and Build the ARM Trusted Firmware (Trusted Firmware A)
+-----------------------------------------------------------
+
+.. code-block:: bash
+
+    $ echo "Downloading and building TF-A..."
+    $ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
+    $ cd trusted-firmware-a
+
+Then build ATF (TF-A):
+
+.. code-block:: bash
+
+    $ export CROSS_COMPILE=aarch64-linux-gnu-
+    $ make PLAT=imx8mp IMX_BOOT_UART_BASE=0x30880000 bl31
+    $ cp build/imx8mp/release/bl31.bin ../
+
+Get the DDR Firmware
+--------------------
+
+.. code-block:: bash
+
+    $ cd ..
+    $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.10.1.bin
+    $ chmod +x firmware-imx-8.10.1.bin
+    $ ./firmware-imx-8.10.1.bin
+    $ cp firmware-imx-8.10.1/firmware/ddr/synopsys/lpddr4*_202006.bin ./
+
+Build U-Boot
+------------
+.. code-block:: bash
+
+    $ export CROSS_COMPILE=aarch64-linux-gnu-
+    $ make verdin-imx8mp_defconfig
+    $ make
+
+Flash to eMMC
+-------------
+
+.. code-block:: bash
+
+    > tftpboot ${loadaddr} flash.bin
+    > setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
+    > mmc dev 2 1 && mmc write ${loadaddr} 0x0 ${blkcnt}
+
+As a convenience, instead of the last two commands one may also use the update
+U-Boot wrapper:
+
+.. code-block:: bash
+
+    > run update_uboot
+
+Boot
+----
+
+ATF, U-Boot proper and u-boot.dtb images are packed into FIT image,
+which is loaded and parsed by SPL.
+
+Boot sequence is:
+
+* SPL ---> ATF (TF-A) ---> U-Boot proper
+
+Output:
+
+.. code-block:: bash
