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 Signed-off-by: Mingkai Hu <Mingkai.Hu@freescale.com> Signed-off-by: Po Liu <Po.Liu@freescale.com>
