driver/power/tplink: use IotStrip instead of deprecated SmartStrip

Since python-kasa 0.7.0, the SmartStrip class is deprecated [1].

The docs state [2]:

  "If you want to continue to use the old API for older devices, you can
  use the classes in the iot module to avoid deprecation warnings."

Do that.
