ide: factor out devices setup from ide_acpi_init()
* Factor out devices setup from ide_acpi_init() to
ide_acpi_port_init_devices().
* Call ide_acpi_port_init_devices() in ide_device_add_all().
While at it:
* Remove no longer needed 'drive' field from struct ide_acpi_drive_link.
There should be no functionality changes caused by this patch.
