ide: remove hwif->autodma and drive->autodma

* hpt34x.c: disable DMA masks for HPT345
  (hwif->autodma is zero so DMA won't be enabled anyway).

* trm290.c: disable IDE_HFLAG_TRUST_BIOS_FOR_DMA flag
  (hwif->autodma is zero so DMA won't be enabled anyway).

* Check noautodma global variable instead of drive->autodma in ide_tune_dma().

  This fixes handling of "ide=nodma" kernel parameter for icside, ide-cris,
  au1xxx-ide, pmac, it821x, jmicron, sgiioc4 and siimage host drivers.

* Remove hwif->autodma (it was not checked by IDE core code anyway) and
  drive->autodma (was set by all host drivers - except HPT345/TRM290 special
  cases - unless "ide=nodma" was used).

While at it:
- remove needless printk() from icside.c
- remove stale FIXME/comment from ide-probe.c
- don't force DMA off if PCI bus-mastering had to be enabled in setup-pci.c
  (this setting was always later over-ridden by host drivers anyway)
