The attached patch enables flashing on the Iwill DK8-HTX board.
Basically, it configures the SuperIO to set the right GPIO pins, so
write protection is disabled.

This patch should help those people that try to use flashrom on an iwill
dk8_htx board, with or without biossavior, on factory BIOS or Linuxbios.

Mondrian
