ide: add struct ide_host (take 3)
* Add struct ide_host which keeps pointers to host's ports.
* Add ide_host_alloc[_all]() and ide_host_remove() helpers.
* Pass 'struct ide_host *host' instead of 'u8 *idx' to
ide_device_add[_all]() and rename it to ide_host_register[_all]().
* Convert host drivers and core code to use struct ide_host.
* Remove no longer needed ide_find_port().
* Make ide_find_port_slot() static.
* Unexport ide_unregister().
v2:
* Add missing 'struct ide_host *host' to macide.c.
v3:
* Fix build problem in pmac.c (s/ide_alloc_host/ide_host_alloc/)
(Noticed by Stephen Rothwell).
