ide: remove ->init_setup_dma from ide_pci_device_t (take 2)
* Make ide_pci_device_t.host_flags u32 and add IDE_HFLAG_CS5520 host flag. * Pass ide_pci_device_t *d to setup-pci.c::ide_get_or_set_dma_base() and use d->name instead of hwif->cds->name. * Set IDE_HFLAG_CS5520 host flag in cs5520 host driver and use it in ide_get_or_set_dma_base() to find out which PCI BAR to use, remove no longer needed cs5520.c::cs5520_init_setup_dma() and ide_pci_device_t.init_setup_dma. This fixes PCI bus-mastering not being checked for CS5510/CS5520 hosts. v2: * It is wrong to check simplex bits on CS5510/CS5520 as v1 did. (Noticed by Alan).
