[flashrom] [Patch] Board enable for Asus P4P800-E Deluxe.

[Luc Verhaegen]

First time i successfully dug one out of an AMI Bios. int16h ax=0xE0
is indeed the ticket. This one has its int16h vector at the standard 
location it seems: 0xF000:0xE82E. Not sure how general this is for AMI.

It does seem that i will require dumps of the F segment for this to 
work though.

Board enable for Asus P4P800-E Deluxe.

Raises what seems to be gpio21.

Uses host controller and Promise Raid Controller for a unique match.
