Set wireless power at init and power off

Browse Source 
Add a new wireless object for controlling WLAN power state. Change the
power sequence to enable WLAN at board init and disable it at power off.

Newer galp5 units sold to customers have an issue where they do not
fully power off. This is apparently somehow caused by `WLAN_PWR_EN`.

The unit received for development do not have this issue.
