wifi: rt2x00: use explicitly signed or unsigned types

On some platforms, `char` is unsigned, but this driver, for the most part,
assumed it was signed. In other places, it uses `char` to mean an
unsigned number, but only in cases when the values are small. And in
still other places, `char` is used as a boolean. Put an end to this
confusion by declaring explicit types, depending on the context.
