mb/purism/librem_whl: Add new board Librem Mini (WHL-U)

Add new librem_whl baseboard and Librem Mini variant.

Tested with SeaBIOS, Tianocore, and Heads payloads.

All functions working normally except SATA, which is limited
via a FSP UDP to 3Gbps until the correct HSIO PHY settings
can be determined.
