Poonam Aggrwal e1dbdd8152 powerpc/mpc85xx:Add support of B4420 SoC
B4420 is a reduced personality of B4860 with fewer core/clusters(both SC3900
and e6500), fewer DDR controllers, fewer serdes lanes, fewer SGMII interfaces and
reduced target frequencies.

Key differences between B4860 and B4420
----------------------------------------
B4420 has:
1. Fewer e6500 cores: 1 cluster with 2 e6500 cores
2. Fewer SC3900 cores/clusters: 1 cluster with 2 SC3900 cores per cluster.
3. Single DDRC
4. 2X 4 lane serdes
5. 3 SGMII interfaces
6. no sRIO
7. no 10G
