libata: add @ap to ata_wait_register() and introduce ata_msleep()
Add optional @ap argument to ata_wait_register() and replace msleep()
calls with ata_msleep() which take optional @ap in addition to the
duration. These will be used to implement EH exclusion.
This patch doesn't cause any behavior difference.
