5bbcf9242d cmd640: fix deadlock on error handling
Stop abusing ide_lock lock (switch to a private locking).

Fixes same issue as fixed by Alan Cox in atiixp host driver with
commit 6c5f8cc33e.

cmd640 is a bit special cause we still need to leave ide_lock for
->set_pio_mode with 'pio' argument == 8/9 (prefetch disable/enable).

8f173b5bf4 ide: fix ide_register_hw() to check hwif->io_ports[]
hwif->hw.io_ports[] and hwif->io_ports[] should be the same but "4drives"
support and scc_pata host driver set only hwif->io_ports[].

To compensate for this check hwif->io_ports[] instead of hwif->hw.io_ports[]
in ide_register_hw() (instead of fixing "4drives" and scc_pata because hwif->hw
is to be removed).

There should be no functionality changes caused by this patch
(sgiioc4.c: ide_proc_register_port() requires hwif->present

  and in init_hwif_siimage() set ->reset_poll method only
  for SATA controllers.

* Rename siimage_pre_reset() to sil_sata_pre_reset(),
  in init_hwif_siimage() set ->pre_reset method only for
  SATA controllers and remove redundant is_sata() call.

* Add CONFIG_BLK_DEV_IDE_SATA #ifdef/#endif to pdev_is_sata()
  so compiler will know to throw out unused SATA code for
  CONFIG_BLK_DEV_IDE_SATA=n case (830 bytes saved on x86-32).

* Bump driver version.

Some minor cleanups while at it:

* Convert sil_{pata,sata}_udma_filter() to use ATA_UDMA* defines.

* In siimage_mmio_ide_dma_test_irq() move 'base' variable
  under 'if (SATA_ERROR_REG)' block.

* Simplify sil_sata_reset_poll() a bit.

* Cache is_sata() result in init_hwif_siimage()

cad221aa82 alim15x3: fix CD_ROM DMA and PIO FIFO settings setup
* Setup CD_ROM DMA and PIO FIFO settings in init_chipset_ali15x3() instead
  of ata66_ali15x3().  The latter is called from init_hwif_common_ali15x3()
  only if DMA base exists (which insists m5529_revision > 0x20).

  This changes makes CD_ROM DMA / PIO FIFO bits being set only once
  and also when "idex=ata66" kernel parameter is used.

* While at it move also chip_is_1543c_e setup from ata66_ali15x3() to
  init_chipset_ali15x3() and check if isa_dev exists before accessing it.
