i945: Reset IGD on boot

This is mostly necessary for reboot, but it doesn't hurt the boot process.
    On reboot explicitely reset the integrated graphics, otherwise the VGABIOS
    might not be able to reinitialize it properly, and you either have a still
    of the last pre-reboot image, garbage or an empty screen, but no text-mode.
