powerpc/p3060: Add SoC related support for P3060 platform

Add P3060 SoC specific information:cores setup, LIODN setup, etc

The P3060 SoC combines six e500mc Power Architecture processor cores with
high-performance datapath acceleration architecture(DPAA), CoreNet fabric
infrastructure, as well as network and peripheral interfaces.
