mainboard/asus/kgpe-d16: Use I/O PCI access in bootblock

The existing code incorrectly used standard PCI access
    calls in the bootblock.  Use the I/O PCI access calls
    as the normal PCI access mechanisms have not yeu been
    set up.

Also ensure the recovery jumper GPIO has been set to
    input mode before reading it.
