[v4,0/4] Add APIs for configurable power options

  The power library contains some variables which are currently set by
defines, hard-coded values or set using sysfs values. In order to
configure these, code changes and recompiles are required, making
configuring these variables tedious.

This patchset introduces some new get/set APIs which allow users and
applications to configure there settings to suit their use-cases.
In addition, CLI options have been added to l3fwd_power to demonstrate
how an application could use these APIs to expose the options to users
without needing code changes to configure them.

---
v4:
* fix return value when scaling_freq_max is not set
* fix mismatching comments

v3:
* move setters from arg parse function to init
* consider 0 as 'not set' for scaling_freq_max
* other minor fixes

v2:
* add doc update for l3fwd-power
* order version.map additions alphabetically

Kevin Laatz (4):
  lib/power: add get and set API for emptypoll max
  lib/power: add get and set API for pause duration
  lib/power: add get and set API for scaling freq min and max with
    pstate mode

Hi Kevin,

We also have documentation for this library under 
`doc/guides/prog_guide/power_man.rst`, which documents methods exposed 
by the PMD power management. That document needs to be updated with the 
new additions :)
