ide-{floppy,tape}: remove debug code for dumping identify data

IDE core supports dumping raw identify data in hdparm friendly format now
so verbose identify dumping in ide-{floppy,tape}.c device drivers (done iff
IDE{FLOPPY,TAPE}_DEBUG_INFO is defined to '1' and it is '0' by default)
is no longer nedeed.
