Add phy-pcie node for using Exynos5440 pcie.
And use the reg-names as "elbi" and "config".
Because the getting configuratioin space address from ranges is old way.
It also is helpful to distinguish more clearly.

Changelog on V2:
- Removes the child-node
- Fixes the typo
- Removes the unnecessary comments
