mb/cwwk: Add CWWK CW-ADL-4L-V1.0 board

This board is the CWWK variant based upon Alder Lake with 4 2.5 GbE
ports, similar boards are available in other port configurations. As a
low cost, relatively high performance board with 4 NICs, it is well
suited for networking or 'homelab' tasks.

CPU: Intel N100 or N350
Memory: DDR5-4800 SODIMM (max 16 GB)
NIC: 4x Intel I226-V 2.5 GbE
Expansion:
- M.2 2230 E key
- M.2 2280 M key
- USB 2.0 header
- Fan header
External ports:
- DC power
- 4x Ethernet
- Display Port
- HDMI
- 4x USB 2.0
- Micro SD

Working:
- Boots Debian 12 with SeaBIOS and EDK II payloads
- Serial port
- External USB ports
- DisplayPort / HDMI
- 4x Intel I226 2.5 GbE NICs
- M.2 ports
- Micro SD slot
- ACPI S3

Not working / not tested:
- Fan (ITE IT8613E)
- Audio
- S0ix
- Internal USB ports

VBT extracted from vendor UEFI firmware version ADLN 0.01 x64
(04/04/2023 11:42:38).
