When the parent router supports "MAC Data Poll Keepalive" method only, using `zb_set_keepalive_timeout()` is equivalent to establishing the poll period. However, if the parent router supports "End Device Timeout Request Keepalive" method, the end device will send End Device Timeout Requests according to the `zb_set_keepalive_timeout()` configuration. These messages have their corresponding End Device Timeout Responses, leading to an increment of the radio usage and consequently, power consumption increase. This commit makes use of `zb_zdo_pim_set_long_poll_interval()` to establish the periodicity of the Data Requests, which determine the latency of the device, while keeping a larger periodicity for the keepalive messages (in case parent router doesn't support "End Device Timeout Request Keepalive" method.
