75b1d97535 ide: convert ide_find_best_mode() users to use ide_max_dma_mode()
ide-timing.h:

* remove handling of DMA modes from ide_find_best_mode() and rename it to
  ide_find_best_pio_mode()

* drop no longer needed "map" argument from ide_find_best_pio_mode()
  and delete needless ->id check

* remove no longer needed XFER_SWDMA and XFER_UDMA* defines

au1xxx-ide.c:

* use ide_max_dma_mode() instead of ide_find_best_mode()

* remove needless CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA #ifdef

amd74xx.c:

* store UDMA masks in amd_ide_chip[] and while at it make "base" field
  to be u8 instead of unsigned long

* convert the driver to use UDMA masks from amd_ide_chip[]

* use ide_max_dma_mode() and ide_find_best_pio_mode() instead
  of ide_find_best_mode()

* delete stale comment from amd74xx_ide_dma_check()

* remove no longer needed AMD_UDMA* defines

via82cxxx.c:

* remove unused DISPLAY_VIA_TIMINGS define

* store UDMA masks in via_isa_bridges[] and while at it make "flags" field
  to be u8 instead of u16

* convert the driver to use UDMA masks from via_isa_bridges[]

* use ide_max_dma_mode() and ide_find_best_pio_mode() instead
  of ide_find_best_mode()

* remove no longer needed VIA_UDMA* defines

pmac.c:

* use ide_max_dma_mode() instead of ide_find_best_mode()

There should be no functionality changes caused by this patch.

c283f5dbe3 ide: make void and rename ide_dma_timeout() method
Since ide_dma_timeout() method's result is discarded, make it return 'void'.
While at it, drop 'ide_' from the method's name, drop the '__' prefix from
the default method's name, and do some cleanups in this method driver-wise:

- in ide-dma.c, au1xxx-ide.c, and pdc202xx_old.c, define/use 'hwif' variable;

- in au1xxx-ide.c, get rid of commented out printk();

- in sl82c105.c, get rid of unnecessary variables.

841d2a9bf1 ide: make void and rename ide_dma_lostirq() method
Since ide_dma_lostirq() method's result is discarded, make it return 'void'.
While at it, rename the method to dma_lost_irq(), drop the '__' prefix from the
default method's name, and do some cleanups in this method driver-wise:

- in aec62xx.c, rename the method in accordance with other drivers, and get rid
  of unnecessary variables there;

- in pdc202xx_old.c, define/use 'hwif' variable;

- in sgiioc4.c, rearrange the code to call the resetproc() method directly.

5cbf79cdb3 ide: add ide_proc_register_port()
* create_proc_ide_interfaces() tries to add /proc entries for every probed
  and initialized IDE port, replace it by ide_proc_register_port() which does
  it only for the given port (also rename destroy_proc_ide_interface() to
  ide_proc_unregister_port() for consistency)
  
* convert {create,destroy}_proc_ide_interface[s]() users to use new functions

* pmac driver depended on proc_ide_create() to add /proc port entries, fix it
  
* au1xxx-ide, swarm and cs5520 drivers depended indirectly on ide-generic
  driver (CONFIG_IDE_GENERIC=y) to add port /proc entries, fix them

* there is now no need to add /proc entries for IDE ports in proc_ide_create()
  so don't do it

* proc_ide_create() needs now to be called before drivers are probed - fix it,
  while at it make proc_ide_create() create /proc "ide" directory

Changes here include removing all of CONFIG_PM while it is being repeatedly
smacked with a lead pipe, moving the BURSTMODE param to a #define (it should
be defined almost always anyway), fixing the rqsize stuff, pulling ide_ioreg_t,
and general cleanups and whatnot.
