mb/kontron/mal10: Add COMe-mAL10 minimal support

This patch adds minimal support for the Kontron COMe-mAL10 module with
the Apollo Lake processor together with Kontron T10-TNI carrierboard.

Working:
  - console (Kontron CPLD)
  - USB2/3
  - Ethernet network
  - eMMC
  - SATA
  - PCIe ports
  - Video/DP (*)

Not tested:
  - Video/LVDS

TODO:
  - HDA (codec IDT 92HD73C1X5, currently disabled)
  - SDIO
  - Documentation

As the payload was used:
  - Tianocore (*)(**)
  - SeaBIOS (*)

(*)  Video works only in linux
(**) Works only with Tianocore "UEFIPayload" payload
edk2-stable201903-1569-g3e63a91
(**) Booting with the "CorebootPayload" crashes:

Tested on COMe module with Intel Atom x5-E3940 processor (4 Core,
1.6/1.8GHz, 9.5W TDP). xubuntu 18.04.2 was used as a bootable OS
(5.0.0-32-generic linux kernel)
