Subject: [PATCH V2] of: platform: Create dummy routines for !CONFIG_OF_ADDRESS

Few routines don't have their dummy counterparts which results in build
failures where these routines are used without CONFIG_OF_ADDRESS
enabled.

Fix those by defining the dummy versions.

V2:
- Rebased again latest rc and resolved conflicts.
- No comments received on V1.
