Kontron Electronics GmbH offers small and powerful SoMs based on the
i.MX8MM including PMIC, LPDDR4-RAM, eMMC and SPI NOR.

Currently there are two SoM models:
  * SL i.MX8MM N8010 with 1GB RAM and 8 GB eMMC
  * SL i.MX8MM N8011 with 2GB RAM and 8 GB eMMC

The matching baseboard has the same form factor and similar interfaces
as the other boards from the Kontron "Board-Line" family, including
SD card, 1G Ethernet, 100M Ethernet, USB Host/OTG, digital IOs, RS232,
RS485, CAN, LVDS or HDMI, RTC and much more.

This adds the basic support for the SoMs and boards. Some things to note:
  * The SoMs use the PCA9450 PMIC. The driver support is pending: [1].
  * Two other patches for the external SPI's spidev compatible and the SPI
    NOR support are pending: [2][3].
  * The graphics and display peripherals (DSI, LVDS, HDMI, GPU, etc.) are not
    supported upstream yet.
  * There seems to be an unresolved issue with the upstream SPI driver for
    i.MX8MM which breaks SPI devices: [4].
