[PATCH] libata: add per-device max_sectors
If a low level driver wants to control max_sectors, it had to adjust
ap->host->max_sectors and set ATA_DFLAG_LOCK_SECTORS to tell
ata_scsi_slave_config not to override the limit. This is not only
cumbersome but also incorrect for hosts which support more than one
devices per port.
This patch adds per-device ->max_sectors. If the field is unset
(zero), libata core layer will adjust ->max_sectors according to
default rules. If the field is set, libata honors the setting.
