Merge "Samsung cleanup 2nd version for S5P SoCs for 3.17" from Kukjin Kim:

Cleanup S5P SoCs for 3.17
- removing s5p64x0 SoCs and s5pc100 SoC in mainline because
  no more user and if it is required next time, it will be
  supported with DT.

where to simplify the include and dependency issues involved with having
so many different platform directories.
It was decided to remove plat-s5pc1xx as some of the support was already
in plat-s5p or plat-samsung, with the S5PC110 support added with S5PV210
the only user was the S5PC100. The S5PC100 specific items where moved to
arch/arm/mach-s5pc100.
