* Add ide_free_port_slot() helper.
* Move ide_init_port_data() call and error printk() from
ide_find_port_slot() to ide_host_alloc_all().
* Make ide_{find,free}_port_slot() take ide_cfg_mtx mutex
and convert them use ide_indexes bitmap to keep track of
reserved port slots.
* Don't set hwif->chipset in ide_host_alloc_all() as it is
no longer necessary.
