PPC: Round VGA BIOS size to page boundary
When giving KVM a slot of a size not on page boundary, it chokes. So let's just round up the VGA BIOS size so nobody complains anymore and we don't need to implement sub-page slots. Required for booting a PPC guest in KVM. Signed-off-by: Alexander Graf <agraf@suse.de>
