Qemu used to be responsible for initialising BIOS info tables, including
memory size information such as e820, in lieu of the virtual BIOS doing it.
I ripped all that out from our diverged tree, and put it in
hvmloader/rombios, but maybe they still do it in upstream qemu. I think it
would be harmless if so, since hvmloader/rombios will overwrite/ignore.
