superio/ite/it8721f/acpi/superio: use IO instead of FixedIO resource 

The fixed I/O resource descriptor macro implies that the device will
only decode 10 of the 16 IO port bits causing aliasing. Use an I/O port
descriptor instead and use Decode16 to tell the OS that this I/O
resource will decode all I/O address bits.
