Add driver data to existing compatible string "sandbox,phy". Add an additional compatible string without driver_data
This will verify that bind command parses, finds and passes the correct driver data to device_bind_with_driver_data() by using driver_data in the second sandbox_phy_ids table entry. In sandbox_phy_bind() a check is added to validate driver_data content.
