Warm reboot can not reset controller qca6390 due to lack of controllable power supply, so causes firmware download failure during enable. Fixed by sending VSC EDL_SOC_RESET to reset qca6390 within added device shutdown implementation. Signed-off-by: Zijun Hu Tested-by: Zijun Hu ---

Warm reboot can not restore qca6390 controller baudrate to default due to lack of controllable BT_EN pin or power supply, so fails to download firmware after warm reboot. Fixed by sending EDL_SOC_RESET VSC to reset controller within added device shutdown implementation. Signed-off-by: Zijun Hu
