Please make MAX_TRIES equivalent to num_evtims, here we are trying to deq 10
events in burst and assume it to succeed but in case event dev doesn't support
burst mode event will be stuck as it will have only 1000 tries instead of 4096.

Same as above service use need to be dependent on INTERNAL_PORT capability.
Also, in software event dev case this can be a valid test but in case of a hw
event dev RTE_EVENT_TIMER_ADAPTER_NUM_MAX number of event devicesmight not be
binded to dpdk. Either we need to provide a API to check how many event devices
are supported or use eventdev_timer_adapter_caps_get_t to get the number.
Thoughts?
