[Impact]
 System cannot detect bluetooth after running power-management/suspend-30-cycles-with-reboots

[Fix]
 Enable BT recovery on Realtek 8852CE FW, FW would detect and recover.

[Test Case]
1. checkbox-cli run com.canonical.certification::power-management/suspend_30_cycles_with_reboots
2. check settings > bluetooth

[Where problems could occur]
just enable a function from kernel and run the code in the fw.
the main risk would be related to FW.
