media: ccs: Ensure control handlers have been set up after probe

If the sensor remains powered on after probe when it is needed again and
the runtime PM usage_count is incremented, the control handler setup for
neither control handler is run.

As this is, in most cases, a needless operation in probe, track the status
of sensor power handling after probe and set up control handlers even if
the device was already active right after probe.
