libata: separate out ata_host_alloc() and ata_host_register()
Reorganize ata_host_alloc() and its subroutines into the following
three functions.
* ata_host_alloc() : allocates host and its ports. shost is not
registered automatically.
* ata_scsi_add_hosts() : allocates and adds shosts associated with an
ATA host. Used by ata_host_register().
* ata_host_register() : takes a fully initialized ata_host structure
and registers it to libata layer and probes it.
Only ata_host_alloc() and ata_host_register() are exported.
ata_device_add() is rewritten using the above functions. This patch
does not introduce any observable behavior change. Things worth
mentioning.
* print_id is assigned at registration time and LLDs are allowed to
overallocate ports and reduce host->n_ports during initialization.
ata_host_register() will throw away unused ports automatically.
* All SCSI host initialization stuff now resides in
ata_scsi_add_hosts() in libata-scsi.c, where it should be.
* ipr is now the only user of ata_host_init(). Either kill it by
converting ipr to use ata_host_alloc() and friends or rename and
move it to libata-scsi.c
