Thomas Abraham be297f0374 ARM: S5P: Move SROM controller IO mapping to plat-s5p for S5P SoCs
This patch modifies the following.

1. Moves the SROM controller mapping from S5PV210 specific code to
   S5P common code. The SROM controller mapping can be used for all
   S5P SoCs.

2. Define the SROM controller physical address for S5P64X0, S5P6442,
   S5PC100, S5PV210 and S5PV310.
