the superio part should placed under the LCP bridge.
for your mainboard,
it should under
"            device pci 1f.0 on end  # LPC bridge
add the superio things like:
            device pci 1f.0 on end  # LPC bridge
            chip superio/winbond/w83627hf
                device pnp 2e.0 on #  Floppy
                    io 0x60 = 0x3f0
                    irq 0x70 = 6
                    drq 0x74 = 2
