exynos5250: clean-ups for clock_init 

This does some clean-up for the exynos5250 clock_init.c:
- No global data.
- Remove some unused #includes
- Hard-code the memory type for Elpida DRAM. This will need to be
  fixed eventually (or the system will be unstable), but is good
  enough for early bring-up and until we finish other re-factoring.
