3e249bc559 event/octeontx: add option to use fpavf as chunk pool
Add compile-time configurable option to force TIMvf to use Octeontx
FPAvf pool manager as its chunk pool.
When FPAvf is used as pool manager the TIMvf automatically frees the
chunks to FPAvf through gpool-id.

7684fcf1f4 event/octeontx: add single producer timer arm variant
When application creates the timer adapter by passing
`RTE_EVENT_TIMER_ADAPTER_F_SP_PUT` flag, we can optimize the arm sequence
by removing the locking overhead.

ea73fed2a6 event/octeontx: start and stop timer device
When application requests to start the timer adapter through
`rte_event_timer_adapter_start`, Octeontx TIMvf ring does the
following:
- Uses mbox to communicate TIMpf driver about,
  * SCLK frequency used to convert ns<->cycles.
  * program the ring control parameters and start the ring.
  * get the exact cycle at which the TIMvf ring has started which can be
  used to estimate the bucket position.

On `rte_event_timer_adapter_stop` i.e stop, Octeontx TIMvf ring does the
following:
- Use mbox to communicate TIMpf driver about,
  * reset the ring control parameters and stop the ring.

f874c1eb15 event/octeontx: create and free timer adapter
When the application requests to create a timer device, Octeontx TIM
create does the following:
- Get the requested TIMvf ring based on adapter_id.
- Verify the config parameters supplied.
- Allocate memory required for
  * Buckets based on min and max timeout supplied.
  * Allocate the chunk pool based on the number of timers.
- Clear the interrupts.

On Free:
- Free the allocated bucket and chunk memory.
- Free private data used by TIMvf.
