scripts/checkpatch.pl: add warnings for static char that could be static const char

Browse Source 
Add warnings for possible missing const uses of
	static char foo[] = "bar"
    that could be
	static const char foo[] = "bar"
and
	static const char *foo[] = {"bar", "baz"}
    that could be
	static const char * const foo[] = {"bar", "baz"}
