for power control of Exynos3250.

Arnd Bergmann suggested that need proper driver instead of static memory mapping.
As Chanho Park reply[2], Sachin Kamat already posted the DT support patch[1]
for memory mapping for SYSRAM.

[2] https://lkml.org/lkml/2014/4/10/161

So, I'm going to re-implement following patch related to static memory mapping
after merged Sachin Kamat patch[1].
