net: mscc: ocelot: strengthen type of "u32 reg" in I/O accessors
The "u32 reg" argument that is passed to these functions is not a plain address, but rather a driver-specific encoding of another enum ocelot_target target in the upper bits, and an index into the u32 ocelot->map[target][] array in the lower bits. That encoded value takes the type "enum ocelot_reg" and is what is passed to these I/O functions, so let's actually use that to prevent type confusion.
