qemu: initialize lapic

Recently qemu stopped doing a basic lapic setup and expects the
firmware to handle this properly (like on real hardware).  So
let's do that so coreboot works properly on qemu 2.4+.

Here is the qemu commit message for the change:

  target-i386: disable LINT0 after reset

  Due to old Seabios bug, QEMU reenable LINT0 after reset. This bug is long gone
  and therefore this hack is no longer needed.  Since it violates the
  specifications, it is removed.
