Pass dimm parameters to populate populate controller options

Because some dimm parameters like n_ranks needs to be used with the board
frequency to choose the board parameters like clk_adjust etc. in the
board_specific_paramesters table of the board ddr file, we need to pass
the dimm parameters to the board file.

* move ddr dimm parameters header file from /cpu to /include directory.
* add ddr dimm parameters to populate board specific options.
* Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.
