Peter Barada 8c4445d266 Pass sdrc timing values through board_sdrc_timings structure
Instead of passing individual registers by value to board_get_mem_timings,
pass a board_mem_timings structure pointer for the board files to fill in.
Pass same structure pointer to write_sdrc_timings.  This saves about
90 bytes of space in SPL.
