ide: add ide_dump_identify() debug helper
* Add ide_dump_identify() debug helper for dumping raw identify data in
the hdparm friendly format (== the identify data can be extracted from
dmesg output and passed to hdparm --Istdin).
* Dump identify data in ide-probe.c::do_identify() if DEBUG is enabled.
