Hardcoded SDMA3 Request Events in load_channel()

[pyaramada]

The issue is in the load_channel() function where SDMA request events are hardcoded to ASRC context 0, despite sdma_chan_config() allowing for custom event configurations via peripheral_config. This behavior disregards the caller's specifications and limits the function's flexibility. Could we update the implementation to dynamically use the events defined in the provided peripheral configuration? This change would enhance adaptability and correctness.

Thank you for your attention to this matter.
