X300: Fix tick and sample rate setting

- Removed incorrect function call to set tick rate in
  x300_radio_ctrl_impl.
- Modified legacy compat layer to properly set tick and sample rates.

These changes eliminate the tick and sample rate warnings during X300
initialization if TwinRX is used and allow for TwinRX to be used
alongside other types of daughterboards in the same X300.
