util/superiotool/smsc.c: Add SCH5504 register dump
There is no datasheet available for this SuperIO, but dumping all possible registers on a Dell Optiplex GX520 resulted in data that was similar to other supported chips. Data also matches what is set in the BIOS, e.g. the parallel and serial ports' addresses.
