[flashrom] [Patch] Board enable for Asus P4B266-LM

This is a resend of the previous patch, now using the intel_ich_gpio_raise function. I have now created a separate function, instead of hooking this code onto another board enable that also raises gpio21 (but with a different ICH). Allan, i know you have given an Ack already, but this is now based on more general infrastructure. Can you give this patch a whirl too? You will have to apply this patch here first though: http://patchwork.coreboot.org/patch/467/raw/ Thanks, Luc Verhaegen.
