[coreboot] qemu

[Vladimir 'φ-coder/phcoder' Serbinenko]

@ron: please provide more information about your qemu: version, how
built, options, patches,... Try -M pc-q35-1.7 and -M pc-i440fx-1.7. Try
specifying --no-kvm and --enable-kvm. Speyifying -cpu may help as well.
From my experience with GRUB, qemu has following flaws:
- From version to version they sometimes do subtle changes which break
firmware.
- On some CPUs kvm bugs or behaves unexpectedly.
