Log:
flashrom: Board enable and autodetection for BioStar P4M80-M4.

Thanks to Reinder for clean room reverse engineering and data sheet diving!

This board is autodetected because there are some good BioStar subsystem IDs.
Matching uses onboard VT6420 SATA RAID with subsystem BioStar 3206 and
onboard UniChrome Pro IGP graphics with subsystem BioStar 1202.
