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

$ ./superiotool -s
./superiotool: invalid option -- s

$ ./superiotool -h
Usage: superiotool [-d] [-V] [-v] [-h]

$ ./superiotool -v
superiotool 0.1
