Iterates through the list of known PCI devices.  If a PCI device is
found with a matching \fIclass\fR, a pointer to its device structure is
returned.  Otherwise, NULL is returned.
A new search is initiated by passing NULL to the \fIfrom\fR argument.
Otherwise if \fIfrom\fR is not NULL, searches continue from next device
on the global list.
