socfpga: SPL and DDR init

This series fixes the SPL support on SoCFPGA and cleans up the DDR init code such that it is becoming remotely mainlinable. After this series, the SPL is capable of booting from both SD/MMC and QSPI NOR.

There is still work to be done, but I'd like to start picking it up so it can land in 2015.10 . Reviews and comments are welcome.
