The rte_wait_until_equal_xxx APIs abstract the functionality of 'polling
for a memory location to become equal to a given value'[1].

Use the API for the rte spinlock and ring implementations.

  spinlock: use wfe to reduce contention on aarch64
  ring: use wfe to wait for ring tail update on aarch64
