ide: add port and host iterators
Add ide_port_for_each_dev() / ide_host_for_each_port() iterators and update IDE code to use them. While at it: - s/unit/i/ variable in ide_port_wait_ready(), ide_probe_port(), ide_port_tune_devices(), ide_port_init_devices_data(), do_reset1(), ide_acpi_set_state() and scc_dma_end() - s/d/i/ variable in ide_proc_port_register_devices() There should be no functional changes caused by this patch.
