Add pcie-phy node for using phy-exynos-pcie.
There are some modifications.
1. Remove the configuration space values in "ranges" property.
- The getting configuration space from ranges is old way.
- Instead, It can be got from "config"
2. Use the reg-names as "elbi", "config".
- Can know the purpose of use with reg-names.
