dm: scsi: Scan the actual number of ports
The scsi_scan_dev() is looping over the number of uc_plat->max_id. The number of actual ports a AHCI controller has can be greater than max_id. Update uc_plat->max_id to make SCSI scan all detected ports. Signed-off-by: Aiden Park <aiden.park@intel.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
