exynos5420: minor clean-up memory related stuff

This cleans up a few minor things (mostly #defines) of the memory code
    for exynos5420, pit, and kirby. Specifically:

- CONCONTROL.empty is read-only, so don't try to set it and also
      get rid of the unneeded DMC_CONCONTROL_EMPTY_ENABLE #define.
    - MEMBASECONFIG* overlaps members of the mem_timings struct and
      are mainboard-dependent anyway, so get rid of 'em.
    - DMC_MEMCONTROL_TP_DISABLE corresponds to a reserved bit. It may
      have been deprecated.
    - Same with TIMING* #defines.
    - Clarify DDR_MODE_* usage and use mem->mem_type when appropriate.
