[RFC 02/14] {cfg,nl}80211: mesh power mode config parameters

[Marco Porsch <marco.porsch@etit.tu-chemnitz.de>]

Possible values for the mesh power mode are presented in the
nl80211_mesh_power_mode enumeration. These modes are active,
light sleep and deep sleep.

power_mode has been added to the mesh config structure to hold the
user-configured default mesh power mode which will be used for new
peer links.
