This commit is necessary to be able to re-use the pinctrl code in early
SPL to properly configure pins.
The problem is that those "static" structures (without explicit
initialization) are placed in the SDRAM area, which corresponds to
u-boot proper (not even SPL).
Hence, when one wants to configure pins before relocation via DTS/DM,
the board hangs (imx6q SoC powered one) as only OCRAM area is available
(0x009xxxxx).
This commit prevents from this issue by moving the imx6_pinctrl_soc_info
structure to data section (from BSS).

Currently the mx6qsabresd board does not boot:
U-Boot SPL 2019.07-rc2 (May 16 2019 - 14:28:55 -0300)
Trying to boot from MMC1
spl: could not find mmc device 0. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
The reason for the boot failure is that that the SPL
size got greater than the 68KB limit (4KB header + 64KB max
size) as explained in include/configs/imx6_spl.h.
Remove the CONFIG_SPL_DM option, so that the SPL binary could
fit into the allowed size and the board can boot again.

This commit adds initial support for the Toradex Apalis iMX8QM 4GB WB IT
V1.0B module. Unlike the V1.0A early access samples exclusively booting
from SD card, they are now strapped to boot from eFuses which are
factory fused to properly boot from their on-module eMMC. U-Boot
supports either booting from the on-module eMMC or may be used for
recovery purpose using the universal update utility (uuu) aka mfgtools
3.0.
Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Gigabit Ethernet
- GPIOs
- I2C
Unfortunately, there is no USB functionality for the i.MX 8QM as of yet.
