Refactor option rom initialization code in coreboot.
- move int15 handler out of the generic code into the mainboard directories of those mainboards that actually use it. - move vbe headers to vbe.h - move function prototypes used in native oprom code to x86.h Change-Id: Idfff5e804ea328f7b5feebac72497c97329320ee Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/255 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones <marcj303@gmail.com>
