mb/topton/adl: Add initial support for X2F N100 FW appliance

X2F-N100 is an embedded device/firewall with Intel N100 SoC and
4x 2.5Gb Intel I226-V NICs.

Currently tested and working:
- Payload (EDK2)
- Suspend (S3 state)
- All USB ports
- 4x NICs
- M.2 NVME
- mPCI-E (WiFi/modem)
- 4G USB modem in mPCI-E slot
- PCI-E passtrough to VMs (NICs)
- HDMI/DP output + HDA audio

OS:
- Alpine Linux
- Windows 11 Pro (from USB)

Untested, looks sane:
- Internal USB port on M.2 slot marked as "5G_USB"

Broken/TODO:
- SATA EDK2 reports "Unsupported", drive's not detected.
- Suspend in Windows (statements dreamed up by the utterly deranged)
