x86: Add Advantech SOM-DB5800/SOM-6867 support
Add support for Advantech SOM-DB5800 with the SOM-6867 installed.
This is very similar to conga-qeval20-qa3-e3845 in that there is a
reference carrier board (SOM-DB5800) with a Baytrail based SoM (SOM-6867)
installed.
Currently supported:
- 2x UART (From ITE EC on SOM-6867) routed to COM3/4 connectors on
SOM-DB5800.
- 4x USB 2.0 (EHCI)
- Video
- SATA
- Ethernet
- PCIe
- Realtek ALC892 HD Audio
Pad configuration for HDA_RSTB, HDA_SYNC, HDA_CLK, HDA_SDO
HDA_SDI0 is set in DT to enable HD Audio codec.
Pin defaults for codec pin complexs are not changed.
Not supported:
- Winbond Super I/O (Must be disabled with jumpers on SOM-DB8500)
- USB 3.0 (XHCI)
- TPM
