Module activation

Because zenpower is using same PCI device as k10temp, you have to disable k10temp first.

1. Check if k10temp is active. lsmod | grep k10temp
2. Unload k10temp sudo modprobe -r k10temp
3. (optional) blacklist k10temp: sudo bash -c 'sudo echo -e "\n# replaced with zenpower\nblacklist k10temp" >> /etc/modprobe.d/blacklist.conf'
4. Activate zenpower sudo modprobe zenpower
