wlan: INI Support for configuring PNO scan cycle iteration.
Driver gets only one timer interval which is hardcoded in
supplicant for 10000ms. So until PNO is disabled firmware
repeats PNO scan for every 10 secs. With this change power
consumption can be reduced by increasing scan interval value
exponentially and after certain number of scan cycle,
which is configurable through INI
