ide: (hopefully) fix VDMA for CS5520
* Set the correct hwif->dma_base for the second channel in
ide_get_or_set_dma_base().
* Remove DMA enable code from cs5520_set_pio_mode(), this can
be handled by the generic ->dma_host_on method now.
* Add VDMA check to ide_config_drive_speed().
* drive->using_dma was never enabled since cs5520 host driver's
->ide_dma_on method overrided the generic ->ide_dma_on (so
__ide_dma_on() was never called, drive->using_dma was never set
and VDMA was never used since it depends on drive->using_dma).
Fix it by using ->dma_host_on method instead of ->ide_dma_on
(also add matching ->dma_host_off method).
