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?
