[U-Boot] [PATCH] omap4: board: change global data pointer to file scope

[Paulraj, Sandeep]

> 
> DECLARE_GLOBAL_DATA_PTR is currently defined within the scope
> of function while it is a global pointer. Change the scope of
> definition to replicate it's global scope. This seems to help
> gcc 4.5 optimizations as well.
