[PATCH v2] staging: sm750fb/sm750.c: mark g_def_fbmode as const pointer

Fix a checkpatch.pl warning for g_def_fbmode by marking the pointer
as const. Ensures it is stored as read-only.

Note: g_fbmode[] is left as non-const as its elements are modified at
runtime by lynxfb_set_fbinfo() and sm750fb_setup().
