[PATCH 1/6] ide: set IDE_AFLAG_DRQ_INTERRUPT in do_identify()

[Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>]

Set IDE_AFLAG_DRQ_INTERRUPT in do_identify() instead of ATAPI
device drivers *_setup() methods.

While at it:
- use ata_id_cdb_intr()

There should be no functional changes caused by this patch.
