Add a bunch of new/tested stuff and various small changes 25

Tested mainboards:
OK:
 - ASRock Fatal1ty 970 Performance and P4i65G
   Reported by anonymous email message ID:
   932677687262b1300eaf14260999d9262c31@guerrillamail.com
   The latter actually had a tested board enable already.

Flash chips:
 - Eon EN25Q128 to PREW (+PREW)
   Reported by Adrian Graham
 - GigaDevice GD25VQ41B to PREW (+PREW)
   Reported by David Hendricks
 - Winbond W39V040FB to PREW (+EW)
   Reported by fjed on IRC

Miscellaneous:
 - Change PCI IDs of "MS-6577 (Xenon)" board enable.
   The previous IDs contained the on-board display adapter which is
   disabled when a dedicated graphics card is installed.
 - Add a note to the README how to overcome the clang warning if only a
   single programmer is enabled.
 - Fix some typo and manpage problems found by lintian
 - r1920 introduced some explicit calls to pkg-config instead of $(PKG_CONFIG).
   This patch corrects that.
 - Make MS-7094 (K8T Neo2-F V2.0) board enable less contestable.
   Previous PCI IDs were board-specific but ot the other of devices
   that could be disabled by the firmware or that vary among
   hardware revions. There are no good alternatives available.
   However, since we always have a DMI decoder available now, we can
   use non-board-specific devices without taking risks. Thanks to
   Uwe Hermann for reporting and testing.
 - Some other small changes to clean up whitespace and fix some warnings
   from Debian's lintian.

Corresponding to flashrom svn r1951.
