[PATCH] staging: sm750fb: constify g_fbmode array

The g_fbmode array contains string pointers that do not need to be
modified. Add the 'const' keyword to lock these pointers, making
the entire array read-only. This allows the compiler to safely move
it into the .rodata section.

Fixes checkpatch warning:
WARNING: static const char * array should probably be static const char * const
