Log:
Further code simplifications and improvements.
Add command line option handling code. The following options
are defined at the moment:
-d|--dump Dump Super I/O registers.
-V|--verbose Verbose mode.
-v|--version Show the superiotool version.
-h|--help Show a short help text.
Per default (no options) we just probe for a Super I/O
and print its vendor, name, ID, version, and config port.
Example:
$ ./superiotool
Found SMSC FDC37N769 Super I/O (id=0x28, rev=0x01) at port=0x03f0
$ ./superiotool -d
Found SMSC FDC37N769 Super I/O (id=0x28, rev=0x01) at port=0x03f0
