    qemu: initialize lapic
    
    Recently qemu stopped doing a basic lapic setup and expects the
    firmware to handle this properly (like on real hardware).  So
    lets 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.
