Lost WIFI connection after suspend.
While this happen, the WIFI module couldn't detect any AP, re-enable module and reboot OS without any help.
There only way to get it back is cold boot.

[Test case]
1. Boot into OS
2. open terminal to keep checking dmesg or check the wifi connection from GUI
3. suspend/resume multiple times
4. check the wifi connection

[Where problems could occur]
What the 2 commits should be safe and won't introduce any regression.
1. Reset AFEDIG register before BB reset in power off sequence
2. Adjust power and clock parameters
