doc: announce ethdev API change for detach flag

The flag RTE_ETH_DEV_DETACHABLE will disappear.

This flag is not needed anymore following the hotplug work done for
v17.08. It can be removed, its function is now implicitly made available
by the relevant EAL and rte_bus implementations.

   Target release for removal of the legacy API will be defined once most
   PMDs have switched to rte_flow.
 
+* ethdev: The device flag advertizing hotplug capability
+  ``RTE_ETH_DEV_DETACHABLE`` is not needed anymore and will be removed in
+  v17.11.
+  This capability is verified upon calling the relevant hotplug functions in EAL
+  by checking that the ``unplug`` ops is set in the bus. This verification is
+  done by the EAL and not by the ``ethdev`` layer anymore. Users relying on this
+  flag being present only have to remove their checks to follow the change.

 * librte_table: The ``key_mask`` parameter will be added to all the hash tables
   that currently do not have it, as well as to the hash compute function prototype.
   The non-"do-sig" versions of the hash tables will be removed
