According to using PHY framework, updates the exynos5440-pcie binding. For maintaining backward compatibility, leaves the current dt-binding. (It should be deprecated.) Recommends to use the Phy Framework and "config" property to follow the designware-pcie binding. If you use the old way, can see "mssing *config* reg space" message. Because the getting configuration space address from range is old way. NOTE: When use the "config" property, first name of 'reg-names' must be set to "elbi". Otherwise driver can't maintain the backward capability.
