powerpc/c29xpcie: add support for C29XPCIE board
C29XPCIE board is a series of Freescale PCIe add-in cards to perform
as public key crypto accelerator or secure key management module. It
includes C293PCIE board, C293PCIE board and C291PCIE board.
- 512KB platform SRAM in addition to 512K L2 Cache/SRAM
- 512MB soldered DDR3 32bit memory
- CPLD System Logic
- 64MB x16 NOR flash and 4GB x8 NAND flash
- 16MB SPI flash
