* create_proc_ide_interfaces() tries to add /proc entries for every probed
and initialized IDE port, replace it by ide_proc_register_port() which does
it only for the given port (also rename destroy_proc_ide_interface() to
ide_proc_unregister_port() for consistency)
* convert {create,destroy}_proc_ide_interface[s]() users to use new functions
* pmac driver depended on proc_ide_create() to add /proc port entries, fix it
* au1xxx-ide, swarm and cs5520 drivers depended indirectly on ide-generic
driver (CONFIG_IDE_GENERIC=y) to add port /proc entries, fix them
* there is now no need to add /proc entries for IDE ports in proc_ide_create()
so don't do it
* proc_ide_create() needs now to be called before drivers are probed - fix it,
while at it make proc_ide_create() create /proc "ide" directory
