wahoo: power: change node owner early to reduce permission denial log spam

Browse Source 
PowerHAL (started in class hal) will try to reset nodes to their initial values,
however the node permission is granted only upon boot_complete which leads some
permission log spam. This CL is to address the logspam.

Test: boot and do powerhint
