opp: Reuse the enabled flag in !target_freq path
The OPP core needs to track if the resources of devices are enabled/configured or not, as it disables the resources when target_freq is set to 0. Handle that with the new enabled flag and remove otherwise complex conditional statements. Tested-by: Rajendra Nayak <rnayak@codeaurora.org> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
