Tighten up board id match table in preparation of upcoming matching
changes.

Some boards are deliberately broken so that we will receive reports
or can remove support later (for instance, for agami aruma, which,
probably is no longer available in the wild).

* Acorp 6A815EPD: make autodetectable.
* Agami Aruma: remove bogus subsystem ids. Due to lacking secondary
  main id, this match will break soon.
* GIGABYTE GA-2761GXDK: Add secondary main id. Subsystem ids are not
  possible as they are all copies of the main ids. Will still require
  -m.
* GIGABYTE GA-M57SLI-S4: add full set of subsystem ids. Will keep
  match name for coreboot name matching.
* GIGABYTE GA-M61P-S3: Add secondary main id. Remove name match.
  Probably has good subsystem ids, but no info was found. So
  deliberately broken match.
* GIGABYTE GA-MA790FX-DQ6: pointless name match.
* IBM x3455: add full ids, remove name match.
* Kontron 986LCD-M: remove full id match as it is bogus. Kontron is
  an embedded vendor and does not bother with subsystem ids, so
  make this board name match only.
* MSI MS-6590 (KT4 Ultra): remove name match.
* MSI MS-7135 (K8N Neo3): add full id set, keep name match for
  coreboot.
* VIA EPIA-N/NL: remove name match.
* VIA PC3500G: remove name match.
