[PATCH] EDD: move code from i386-specific locations to generic

From: Matt Domsch <Matt_Domsch@dell.com>

Three patches to move the BIOS Enhanced Disk Drive code from i386-specific
locations into more generic locations, which will allow it to be used on
x86-64 as well.

move edd.h from include/asm-i386 to include/linux

arch/i386/kernel/setup.c
