Split flash_enable.c into chipset_enable.c and board_enable.c

This splits up the ROM Write enable code into chipset specific and
board specific parts. This of course means that a lot of code is
plainly moved about.

* Allows for linuxbios name matching and pci-subsystem id matching.
  The latter uses a double set to properly distuinguish boards despite
  of some known vendors being lax about it.
* Fixes GPIO15 being raised on every VT8235 southbridge, regardless of what
  that line actually controls; rom on EPIA-M, backlight on mitac 8999 laptop.
* Adds flashrom support for Asus A7V400-MX (KM400 + VT8235)
* Island aruma was renamed agami aruma, the board specific code now got
  adjusted. A set of pci-ids was retrieved from source code.

Corresponding to flashrom svn r99 and coreboot v2 svn r2581.
