* 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().
