Change real mode API to allow passing intXX number or entry point and
some register values from C. This theoretically fixes non-vga option roms, but it also allows to use the same assembler code for option roms and vsm. It will also make using the bootsplash without yabel a lot easier. Factor out and improve BDA setup, do some rom segment setup for those option roms that need it. Don't call the coreboot exception handler if an exception occurs in real mode. It's only partly usable, but mainly the Kontron 986LCD-M (and other i945GM boards) choke on an exception #6 (invalid opcode). This particular issue is not introduced by the changes in this patch but has been around for quite a while at least.
