X300: Fix for channel 1 failure to ACK a TX burst.

- Added mapping from radio block and port to channel in legacy compat layer.
- Improved parsing of stream args and added parsing of radio ID and port parameters for each channel.
- Added proper programming of the response SID based on the new radio ID and port parameters.
