Implement sensing_init(): 1) create sensors from device tree 2) sequence sensors following node dependency ordering rule generated by Zephyr DTS 3) initial each sensor, includes: a) creating sensor connection between reporter and client, b) calling sensor init callback, c) setting sensor state Implement sensing_open_sensor(): 1) malloc connection from reporter to application 2) bind connection Implement sensing_close_sensr(): 1) unbind connection 2) free connection from reporter to application Implement sensing_set_config(): 1) call set_interval 2) cann set_sensitivity Implement sensing_get_config(): 1) call get_interval 2) call get_sensitivity Signed-off-by: Guangfu Hu <guangfu.hu@intel.com>
