libata: implement PMP helpers
Implement helpers to test whether PMP is supported, attached and determine pmp number to use when issuing SRST to a link. While at it, move ata_is_host_link() so that it's together with the two new PMP helpers. This change simplifies LLDs and helps making PMP support optional. Signed-off-by: Tejun Heo <htejun@gmail.com>
