mainboard/system76: Add System76 Lemur Pro (lemp9)

The System76 Lemur Pro (lemp9) is an upcoming laptop computer. Support
in coreboot is developed by System76 and provided as the default
firmware option. Testing is done on a pre-production model expected to
be identical from a firmware perspective to the production model.
