ide: do complete DMA setup in ->init_dma method (take 2)

* Make ide_hwif_setup_dma() return an error value.

* Pass 'const struct ide_port_info *d' instead of 'unsigned long dmabase'
  to ->init_dma method and make it return an error value.

* Rename ide_get_or_set_dma_base() to ide_pci_dma_base(),
  change ordering of its arguments and then export it.

* Export ide_pci_set_master().

* Do complete DMA setup inside ->init_dma method and update ->init_dma
  users accordingly.

* Sanitize code for DMA setup in ide_init_port().

v2:
* Fix for CONFIG_BLK_DEV_IDEDMA_PCI=n configs
  (from Jiri Slaby <jirislaby@gmail.com>):

  Fix following compiler warning by returning EINVAL:

  In file included from ANYTHING-INCLUDING-IDE.H:45:
  include/linux/ide.h: In function ‘ide_hwif_setup_dma’:
  include/linux/ide.h:1022: warning: no return statement in function returning non-void
