sandbox: phy: add driver_data for bind test cmd

Browse Source 
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.
