The rate constraints in this driver are shared between all device instances. It should not be (and is not) modified at runtime, so make them const.
While we are at it also change the type of the rates array from u32 to unsigned int. While both resolve to the same type, u32 is usually used to empathize that the value is for a 32-bit hardware register or similar which makes it slightly confusing in this context.
