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.
