libata: make ata_port_type const
Make this const as it is only stored in the const field of a device structure. Make the declaration in header const too. Structure found using Coccinelle and changes done by hand. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
