doc: remove obsolete deprecation notice for power library

Remove notice announcing an already-implemented change.

In 19.05, rte_power_set_env was changed to return -1 in cases where
the environment was already set up, and for the same release, a
deprecation notice was added.
This patch removes that notice.

The API change was tested by calling rte_power_set_env twice. The first
call succeeded, and the second call failed, as expected.

 * metrics: The function ``rte_metrics_init`` will have a non-void return
   in order to notify errors instead of calling ``rte_exit``.
 
-* power: ``rte_power_set_env`` function will no longer return 0 on attempt
-  to set new power environment if power environment was already initialized.
-  In this case the function will return -1 unless the environment is unset first
-  (using ``rte_power_unset_env``). Other function usage scenarios will not change.

 * cmdline: ``cmdline`` structure will be made opaque to hide platform-specific

   original structure will be kept until DPDK 21.11.
