ide: remove drive->driveid
* Factor out HDIO_[OBSOLETE,GET]_IDENTITY ioctls handling
to ide_get_identity_ioctl().
* Use temporary buffer in ide_get_identity_ioctl() instead
of accessing drive->id directly.
* Add ide_id_to_hd_driveid() inline to convert raw id into
struct hd_driveid format (needed on big-endian).
* Use ide_id_to_hd_driveid() in ide_get_identity_ioctl(),
cleanup ide_fix_driveid() and switch ide to use use raw id.
* Remove no longer needed drive->driveid.
This leaves us with 3 users of struct hd_driveid in tree:
- arch/um/drivers/ubd_kern.c
- drivers/block/xsysace.c
- drivers/usb/storage/isd200.c
While at it:
* Use ata_id_u{32,64}() and ata_id_has_{dma,lba,iordy}() macros.
There should be no functional changes caused by this patch.
