ide: add struct ide_tp_ops (take 2)
* Add struct ide_tp_ops for transport methods.
* Add 'const struct ide_tp_ops *tp_ops' to struct ide_port_info
and ide_hwif_t.
* Set the default hwif->tp_ops in ide_init_port_data().
* Set host driver specific hwif->tp_ops in ide_init_port().
* Export ide_exec_command(), ide_read_status(), ide_read_altstatus(),
ide_read_sff_dma_status(), ide_set_irq(), ide_tf_{load,read}()
and ata_{in,out}put_data().
* Convert host drivers and core code to use struct ide_tp_ops.
* Remove no longer needed default_hwif_transport().
* Cleanup ide_hwif_t from methods that are now in struct ide_tp_ops.
While at it:
* Use struct ide_port_info in falconide.c and q40ide.c.
* Rename ata_{in,out}put_data() to ide_{in,out}put_data().
v2:
* Fix missing convertion in ns87415.c.
There should be no functional changes caused by this patch.
