amd74xx: remove amd_ide_chips table

* Remove no longer needed assertion from amd74xx_probe().

* Factor out cable detection for AMD7409 to amd7409_cable_detect() and for
  chipsets >= AMD7411 to amd7411_cable_detect().

* Use dev->vendor and dev->device instead of amd_config->udma_mask when
  selecting cable detection method and checking for broken FIFO support in
  init_chipset_amd74xx().

* Remove no longer needed AMD_BAD_FIFO define.

* Add 'swdma' parameter for setting .swdma_mask to DECLARE_AMD_DEV() macro.

* Add 'udma' parameter for setting .udma_mask to DECLARE_{AMD,NV}_DEV() macro.

* Keep a copy of a current amd74xx_chipsets[] entry in amd74xx_probe()
  in order to fix ->swdma_mask on early AMD7409 revisions and ->udma_mask
  on Serenade mainboards.

* Remove no longer needed fixups from init_chipset_amd74xx()
  and AMD_CHECK_{SWDMA,SERENADE} defines.

* Move printing banner message from init_chipset_amd74xx() to amd74xx_probe(),
  also remove incorrect comment while at it.

* Use hwif->ultra_mask instead of amd_config->udma_mask in amd_set_drive().

* Add 'udma_mask' argument to amd_set_speed() and pass UDMA mask from
  amd_set_drive() instead of using amd_config->udma_mask.

* Move amd_config->base from AMD_* defines to users of these defines and add
  0x40 the defined values.  Then add amd_offset() inline helper for selecting
  offset from 0x40 base (needed for nVidia controllers) and finally use it in
  amd_set_speed(), amd7411_cable_detect() and init_chipset_amd74xx() instead
  of amd_config->base.

* Remove no longer needed AMD_BAD_SWDMA define, ->{swdma,ultra}_mask setup
  from init_hwif_amd74xx(), amd_{config,chipset} variables and amd_ide_chips
  table.

* Fix init_chipset_amd74xx() comment.

* Bump driver version.

There should be no functionality changes caused by this patch.
