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