ide: move read_sff_dma_status() method to 'struct ide_dma_ops'
Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops' to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only required for SFF-8038i compatible IDE controller drivers (greatly cutting down the number of initializers) as its only user (outside ide-dma-sff.c and such drivers) appears to be ide_pci_check_simplex() which is only called for such controllers...
