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.
