isd200: make it 'struct hd_driveid'-free

* Factor out debug dump of id from isd200_get_inquiry_data()
  to isd200_dump_driveid().

* Change id field in struct isd200_info from 'struct hd_driveid *id'
  to 'u16 *id' and update driver accordingly.

* Include <linux/ata.h> directly instead of through <linux/hdreg.h>.

While at it:

* Use ata_id_u32() and ata_id_has_lba() macros.

There should be no functional changes caused by this patch.
