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).

The four SATA ports on the mainboard are provided by an onboard ASMedia
ASM1064B PCIe-to-SATA bridge. Unlike other mainboards in the tree using
an ASMedia ASM1061 or ASM1062 PCIe-to-SATA bridge, the ODROID-H4+ comes
with a SPI flash chip for the ASM1064B and does not seem to have issues
regarding PCIe power management (e.g. ASPM) or unusable SATA AHCI mode.

The ODROID-H4 comes with a single 16 MiB SPI flash chip. The ODROID-H4+
and the ODROID-H4 Ultra feature Dual BIOS, consisting of another 16 MiB
SPI flash chip and a 3-pin header to select between them. The board can
be flashed internally or using a SOIC-8 clip, but the M.2 slot may need
to be empty for the clip to fit.

Working:

 - DDR5 SO-DIMM slot
 - All SATA ports on ASMedia ASM1064B PCIe-to-SATA controller
 - UART to emit spam
 - All video outputs (FSP GOP only lights up one output at a time)
 - All USB ports (on the Ethernet connectors and on EXT_HDR1)
 - M.2 M connector (PCIe only)
 - PCIe power management
 - Ethernet NICs
 - eMMC
 - HD audio codec and display audio
 - S3 suspend/resume
 - SeaBIOS <current version>
 - MrChromebox edk2 <current version>
 - Super I/O HWM on Linux (using out-of-tree it87 kernel module)
 - Booting Arch Linux from NVMe and SATA
 - Booting Windows 10 from NVMe

Not working:

 - PECI: undocumented protocol and undocumented Super I/O
 - Resuming on Windows 10 BSODs with `VIDEO_TDR_FAILURE`

Untested:

 - Fan curves: may need to lower the temperature limits a bit
