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.

spl: Provide more space to be used for storing SPL on imx28 OCRAM
With the current configuration provided in mxsimage{-spl}.mx28.cfg the
size of SPL binary has been constrained to 32 KiB, due to "LOAD IVT"
command with 0x8000 offset.
The problem was that, the imx28 ROM takes the u-boot.sb and then
extracts from it the IVT header and places it on the 0x8000 OCRAM offset
overwriting any valid (i.e. loaded from eMMC or SPI-NOR) SPL code. This
bug was unnoticed as the overwrite size was just 32 bytes, so the
probability that some important code is altered was low.
However, in the XEA board (where the SPL size is ~39KiB), the overwritten
data was `(struct dm_spi_ops *) 0x800c <mxs_spi_ops>`, which is used
during the boot process.
As a result the SPL execution code hanged with "undefined instruction"
abort as callbacks (with wrong addresses) from it were called.
The fix is to change the OCRAM's offset where IVT is loaded to 0xE000,
so the SPL can grow up to ~57KiB (the maximal size of OCRAM memory
available is 0xE3FC).
