batman-adv: Add elp_interval hardif genl configuration
The ELP packets are transmitted every elp_interval milliseconds on an
slave/hard-interface. This value can be changed using the configuration
interface.
The BATADV_CMD_SET_HARDIF/BATADV_CMD_GET_HARDIF commands allow to set/get
the configuration of this feature using the u32 BATADV_ATTR_ELP_INTERVAL
attribute.
