IWL_POWER_AC and IWL_POWER_BATTERY are just two power modes. IWL_POWER_=
AC=20
would be the default power mode when we're in AC (no power saving) and=20
IWL_POWER_BATTERY would be the default power mode when we're in battery=
=20
(power saving mode). That's why we set IWL_POWER_ENABLED flag with=20
IWL_POWER_BATTERY, because it is the only power mode that saves power.

We can change to IWL_POWER_BATTERY or IWL_POWER_AC in any moment.

This patch, depending if power management is enabled or not, sets which=
 power=20
mode we should use, Then, it checks if we're already using this mode or=
 not.
