Action :
1. Improve : Call ocpp_set_profile_req() when the system mode on SYS_MODE_TERMINATING.
2. Improve : If temperature over 75 derating PWM duty to 80% and recover if temperature less than 65.
3. Fixed : Charging profile limit equal 0 can not back to SYS_MODE_CHARGING fixed.
4. Merge : Module_Debug.c from AW-Regular to Noodoe project.
5. Merge : Module_ConfigTools.c from AW-Regular to Noodoe project.
6. Added : temCoefficient variable.
