mb/asus/p8z77-m: Enable Port 80 UART
Copied this bit from asus/p8z77-m_pro, without it a GRUB2 payload will
get stuck in an endless loop showing
Unknown key 0xff detected
whenever there is an USB device (such as a keyboard) connected.
In this mode GRUB2 is so busy showing this message repeatedly that no
other keypress ever gets handled, and thus no other remedy is possible
than a reset via mb pins and unplugging the USB device.
