mb/system76/adl: Add Lemur Pro 11 as a variant
The Lemur Pro 11 (lemp11) is an Alder Lake-U board.
Tested with a custom TianoCore UefiPayloadPkg.
Working:
- PS/2 keyboard, touchpad
- DIMM slot (with NMSO480E82-3200EA00)
- M.2 NVMe SSD (with MZVL2500HCJQ)
- M.2 SATA SSD (with WDS100T2B0B)
- All USB ports
- SD card reader
- Webcam
- WiFi/Bluetooth
- Integrated graphics using Intel GOP driver
- HDMI output
- DisplayPort output over USB-C
- Internal microphone
- Internal speakers
- Combined headset + mic 3.5mm audio
- S0ix suspend/resume
- Booting Pop!_OS Linux 22.04 with kernel 6.1.11
- Internal flashing with flashrom v1.2-1203-gf4ddd3234330
Not working:
- On-board RAM: Requires CB:65567
- Detection of devices in TBT slot on boot
