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.
