[libata] add new ->bmdma_setup hook
In order to support some new taskfile protocols, particularly ATAPI,
the setup-and-start-DMA hook needs to be split into its component
pieces, 'setup' and 'start'.
For PCI IDE-style controllers, most of the code is moved into the
'setup' portion, with the 'start' portion only flipping a single
bit in hardware.
