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.
