Add the nl80211_mesh_power_mode enumeration which holds possible values for
the mesh power mode. These modes are unknown, active, light sleep and
deep sleep.
Add power_mode entry to the mesh config structure to hold the user-configured
default mesh power mode. This value will be used for new peer links.
Add the dot11MeshAwakeWindowDuration value to the mesh config. The awake window
is a duration in TU describing how long the STA will stay awake after
transmitting its beacon in PS mode.
Add the station parameters and flags for future userspace access.
