* Sets NFC controller always on feature.
* <p>This API is for the NFCC internal state management. It allows to discriminate
* the controller function from the NFC function by keeping the NFC Controller on without
* any NFC RF enabled if necessary.
* <p>This call is asynchronous. Listen for {@link #ACTION_ALWAYS_ON_STATE_CHANGED}
* broadcasts to find out when the operation is complete.
* <p>If this returns true, then either NFCC is already on, or
* a {@link #ACTION_ALWAYS_ON_STATE_CHANGED} broadcast will be sent to indicate
* a state transition.
* If this returns false, then there is some problem that prevents an attempt to turn NFCC on.
* @param value if true the NFCC will be kept on (with no RF enabled if NFC adapter is
* disabled), if false the NFCC will follow completely the Nfc adapter state.
* @throws UnsupportedOperationException if FEATURE_NFC is unavailable.
