rsi: miscallaneous changes for 9116 and common

Below changes are done:
* Device 80MHz clock should be disabled for 9116 in 20MHz band.
* Default edca parameters should be used initially before
  connection.
* Default TA aggregation is 3 for 9116.
* Bootup parameters should be loaded first when channel is
  changed.
* 4 byte register writes are possible for 9116.
