mb/asus/f2a85-m_pro: Clean up super-I/O GPIO settings
Drop useless writes to read-only registers and don't re-write default 0x00 values. In detail: * Don't write read-only status registers. * Don't try to write input bits in data registers (iow. mask data values: `data &= ~io`). * Don't write data registers if all GPIOs are set as inputs (`io == 0xff`). * Don't write default 0x00 for inversion and multiplex registers. Note: Both GPIO0 and WDT1 values look spurious. Maybe they were dumped with the virtual devices disabled?
