[WIP] mb/hardkernel/odroid-h4: Add support for ODROID-H4 series

Add support for the ODROID-H4 family of boards. Tested on an ODROID-H4+
board, but all of them use the same PCB (with different components).

Currently working on getting things set up properly. Expect some chaos.

Working:

- DDR5 SO-DIMM slot
 - At least one SATA port on ASMedia ASM1064B PCIe-to-SATA controller
 - UART to emit spam
 - All video outputs (FSP GOP only lights up one output at a time)
 - Booting to Linux on SATA SSD with SeaBIOS <current version>

Not working:

- USB ports: need to tell the Super I/O to enable power to the ports
   on the built-in connectors (below the Ethernet ports)
 - Dual BIOS: flash chip switching mechanism is very sus

Untested:

- The other SATA ports
 - Fan control: seems wonky
 - Rest of Super I/O config: needs exorcism
 - HDA codec: SPDIF is untestable
 - Ethernet NICs
 - M.2 slot (PCIe only, no SATA lanes)
 - S3 suspend/resume
 - edk2 payload
 - Windows (with edk2 payload)
 - PCIe ASPM and friends
