Are you sure this line should be deleted?

I think the case VT1211_SP2: should go extra:

case VT1211_SP1:
        pnp_write_config(dev, index + 0, (iobase >> 2) & 0xff);
        break;
case VT1211_SP2:
        pnp_write_config(dev, index + 0, (iobase >> 2) & 0xff);
        pnp_write_config(dev, 0x27, 0x00); // Serial Port 2 Multi Function Pin Select
        break;

Can you please try and see if this does the job?
