ethdev: deprecate DEFERRED device state

  Add a deprecation notice to remove RTE_ETH_DEV_DEFERRED state, but this
is mostly a reminder because of a missing target.
It doesn't worth to break the ABI because of this change and removal
can be done when ethdev ABI version increased.

In this release we already break the ABI for ethdev, instead of putting this
deprecation notice in, I will send a patch to remove RTE_ETH_DEV_DEFERRED, since
it is not used in current code, it should be trivial and safe change.
