cmd640 is PIO only while bf54x and icside are BMDMAs. Fix
inheritance. bf54x and icside are quasi-BMDMA controllers which don't
use the standard BMDMA registers so they don't initialize bmdma_addr
and inherited from sff to avoid the default mode_filter which disables
DMA modes if bmdma_addr is not initialized.
This patch makes both drivers explicitly specify ->mode_filter to
ATA_OP_NULL while inheriting from ata_bmdma_port_ops. These will be
removed by the next patch.
This patch makes all and only BMDMA drivers inherit from
ata_bmdma_port_ops to ease further SFF/BMDMA separation.
