[PATCH] ata: ahci_platform: fix DT probing

[Rob Herring]

From: Rob Herring <rob.herring@xxxxxxxxxxx>

The change in commit 904c04feaf13ed "ahci_platform: Add the board_ids..."
doesn't work for the DT probing case as platform_get_device_id returns
NULL. Pick the default ahci_port_info in this case.
