davinci: da850/omap-l138: create static map for SRAM 



Create static map for internal SRAM and populate SRAM base
and size in soc_info structure to allow SRAM allocation
functions from arch/arm/mach-davinci/sram.c to work.

On DA850 SRAM is used for suspend-to-RAM implementation
in places where DDR2 cannot be accessed as its clocks are
stopped.
