Currently, rx_port_value is a single unsigned int that gets overwritten when slim_rx_mux_put() is called for any RX mux, then the same value is read when slim_rx_mux_get() is called for any of them. This results in slim_rx_mux_get() reporting the last value set by slim_rx_mux_put() regardless of which SLIM RX mux is in question.

Turn rx_port_value into an array and store a separate value for each SLIM RX mux.
