mb/clevo/kbl-u: Add Clevo N240BU as variant

This is the white label device also sold as TUXEDO Book BU1406.

Extracted Video BIOS Option ROM has ID 8086,0406, but the ID of the
graphics device differs, but will be mapped to the correct ID.

The system has the subsystem ID below:

Subsystem: CLEVO/KAPOK Computer Xeon E3-1200 v6/7th Gen Core Processor Host Bridge/DRAM Registers

1.  SeaBIOS rel-1.14.0-14-g748d619 initializes the display with VBIOS
    Option ROM.
2.  Using GOP for graphics initialization works.
3.  Grml 2020.06 on USB flash drive boots.
4.  SPI Flash Console works.
5.  Debian Sid/unstable with Linux 5.9.6 boots from the NVMe SSD.
6.  ACPI S3 resume/suspend works (`freeze`)

Not working:

1.  Function keys (EC ACPI missing)
2.  Webcam
