ide: make ide_hwif_t.ide_dma_host_on void (v2)
* since ide_hwif_t.ide_dma_host_on is called either when drive->using_dma
== 1
or when return value is discarded make it void, also drop "ide_" prefix
* make __ide_dma_host_on() void and drop "__" prefix
v2:
* while at it rename atiixp_ide_dma_host_on() to atiixp_dma_host_on()
and sgiioc4_ide_dma_host_on() to sgiioc4_dma_host_on().
