Revision 2821

 * Convert the NSC code to the common code structure all other Super I/Os use.

 * Improve the --verbose output a bit more. Print the "Probing..." text for
   all Super I/Os and if a Super I/O is not known, show the data we were
   able to read from the chip (what data this is is very vendor/chip specific).

 * Thus the common no_superio_found() is dropped, it's not useful.
   The "read from 0x20" part was wrong for all Super I/Os other than the
   NSC ones anyway.

 * Winbond: For the 'olddevid' only use bits 3..0, mask away the others.

 * SMSC: Print which ID registers we try to read (in --verbose mode).

 * Minor cosmetic fixes.
   * Rename PC8374 to PC8374L (as per datasheet).
   * Rename probe_idregs_simple() to probe_idregs_nsc().
   * Rename dump_readable_ns8374() to dump_readable_pc8374l().
