For being able to bind ata devices against acpi devices, scsi_bus_type
needs to be set as bus in struct acpi_bus_type. So add wrapper to
scsi_lib to accomplish that.

   You don't have to enclode declarations into #ifdef.

+struct acpi_bus_type;
+
+extern int

   'extern' is the default memory class for function, no need to specidy it.
And don't break the line here.

+scsi_register_acpi_bus_type(struct acpi_bus_type *bus);
+
+extern void

   Same comment.

+scsi_unregister_acpi_bus_type(struct acpi_bus_type *bus);
