    tools/firmware: use a canned config for seabios
    
    The use of seabios defconfig kills boot performance of Windows guests
    because the default is for the int13 handler to use PIO when accessing
    the emulated IDE device.
    
    By instead using a canned configuration with the ATA settings overridden
    to enable DMA access (and also wider PIO) boot performance is markedly
    improved without the need to use a different (and possibly not supported)
    device model.
    
    This patch adds the canned configuration into tools/firmware and modifies
    the Makefile rule to copy it into place.
