This is a forward-port of Compulab's downstream commit
against linux 4.9.11, including updates to work with
more recent kernels.
Original commit message:
The SB-IOT-iMX7 base board together with CL-SOM-iMX7
SoM forms SBC-IOT-iMX7 single board computer.
SBC-IOT-iMX7 is a single board computer optimized for
industrial control and monitoring, extensive wireless
and wired connectivity, ideal solution for
cost-sensitive systems. It is based on the Freescale
i.MX7 system-on-chip. SBC-IOT-iMX7 is implemented with
the CL-SOM-iMX7 System-on-Module providing most of the
functions,and SB-IOT-iMX7 carrier board providing
additional peripheral functions and connectors.

https://www.compulab.com/products/sbcs/sbc-iot-imx7-nxp-i-mx-7-internet-of-things-single-board-computer/
This commit adds basic board support, including:
* SD-card (note that write-protect is not connected
on this carrier board)
* SPI (available on expansion header)
* i2c3 & i2c4 (including bus recovery information)
* additional UARTs
* all USB ports
* SNVS powerkey
Compared to the downtream commit, this commit doesn't
add / enable the PCIe and LCD interface, as PCIe
support needs an additional patch to the PCI controller
first, and I can't test the LCD.

v3:
* enable snvs_pwrkey node
v2:
* use standard uart-has-rtscts instead of fsl,uart-has-rtscts
ARM: dts: imx7d: sbc-iot-imx7: has a power key
