arm: socfpga: Repair SoCrates board

This board was constantly parasiting on the CV SoCDK, so split it
into it's own separate directory. Moreover, the board config was
missing important bits, like simple-bus support in SPL, the DRAM
configuration was incorrect and the DTS was also missing the pre
reloc bits.
