powerpc/85xx: Add C29x SoC support
The Freescale C29x family is a high performance crypto co-processor.
It combines a single e500v2 core with necessary SEC engine. There're
three SoC types(C291, C292, C293) with the following features:
- 512K L2 Cache/SRAM and 512 KB platform SRAM
- DDR3/DDR3L 32bit DDR controller
- One PCI express (x1, x2, x4) Gen 2.0 Controller
- Trust Architecture 2.0
- SEC6.0 engine
