mb/asus/p8z77-m: Drop GPIO by I/O
Per Fabian Groffen grobian@gentoo.org in CB:75145:
This particular setting results in
[ERROR] PNP: 002e.308 missing read_resources
The underlying root cause was fixed by commit f5b993de4fcf (sio/nuvoton/nct6779d: Correct GPIOBASE virtual LDN). However, to make GPIO by I/O work requires setting up an I/O port resource here and a generic LPC I/O decode at southbridge/intel/bd82x6x, and both weren't done. Even if done, this newfound capability still doesn't offer much.
