Follow-up to commit 5c05ff68b9a9b40a9be949497e0aa980185565cf
("ide: switch to DMA-mapping API"):
* pci_{alloc,free}_consistent() -> dma_{alloc,free}_coherent()
in ide_{allocate,release}_dma_engine().
* Add ->prd_max_nents and ->prd_ent_size fields to ide_hwif_t
(+ set default values in ide_allocate_dma_engine()).
* Make ide_{allocate,release}_dma_engine() available also
for CONFIG_BLK_DEV_IDEDMA_SFF=n. Then convert au1xxx-ide.c,
scc_pata.c and sgiioc4.c to use them.
* Add missing ->init_dma method to scc_pata.
This patch also fixes:
- ->dmatable_cpu leak for au1xxx-ide
- too early realease of ->dmatable_cpu for scc_pata
- wrong amount of ->dmatable_cpu memory being freed for sgiioc4
While at it:
- remove superfluous ->dma_base check from ide_unregister()
- return -ENOMEM on error in ide_release_dma_engine()
- beautify error message in ide_release_dma_engine()

* 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:

Make drive->id an unnamed union so id can be accessed either by using
'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing
drive->id users accordingly (using 'u16 *id' when possible).
This is an intermediate step to make ide 'struct hd_driveid'-free.
While at it:
- Add missing KERN_CONTs in it821x.c.
- Use ATA_ID_WORDS and ATA_ID_*_LEN defines.
- Remove unnecessary checks for drive->id.
- s/drive_table/table/ in ide_in_drive_list().
- Cleanup ide_config_drive_speed() a bit.
- s/drive1/dev1/ & s/drive0/dev0/ in ide_undecoded_slave().

Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes,
judging from the code immediately preceding this check. So, we must never try
to "split" the PRD for TRM290.
This is probably never hit anyway -- with the DMA buffers aligned to at least
512 bytes and ATAPI DMA not being used for non block I/O commands...
