arm: socfpga: Split SoCFPGA configuration

Split the SoCFPGA configuration into SoC-specific part which is
common for all boards (socfpga_cyclone5_common.h) and a board
specific part. There is currently only one board, which is the
generic SoCFPGA board (socfpga_cyclone5.h), but there are more
to come.

This is necessary due to various features of the boards, which
unfortunatelly cannot be autodetected.
