firmware: socfpga: set APPLYCFG after loading bitstream
To make changes to the SDRAM controller effective, the APPLYCFG bit must
be set after programming the bitstream to the FPGA. This has to be done
without any SDRAM usage. Therefore copy the function to execute to the
OCRAM and execute it from there.
