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