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. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
