* Rename 'simplex_stat' variable to 'dma_stat' in ide_get_or_set_dma_base().
* Factor out code for forcing host out of "simplex" mode from
ide_get_or_set_dma_base() to ide_pci_clear_simplex() helper.
* Add IDE_HFLAG_CLEAR_SIMPLEX host flag and set it in alim15x3 (for M5229),
amd74xx (for AMD 7409), cmd64x (for CMD643), generic (for Netcell) and
serverworks (for CSB5) host drivers.
* Make ide_get_or_set_dma_base() test for IDE_HFLAG_CLEAR_SIMPLEX host flag
instead of checking dev->device (BTW the code was buggy because it didn't
check for dev->vendor, luckily none of these PCI Device IDs was used by
some other vendor for PCI IDE controller).

* 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()

* 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.
