Changes in library: - enableProximity() function is to enable or disable proximity sensor - enableIlluminance() function is to enable or disable illuminance sensor - run clang-format Changes in example: - proximity and illuminance kernel IIO-based driver init state is power off, require enable before read out sensor data. Sleep time is needed after enable, the sleep time may vary on different platform. - run clang-format Signed-off-by: Lay, Kuan Loon <kuan.loon.lay@intel.com> Signed-off-by: Mihai Tudor Panu <mihai.tudor.panu@intel.com>
