[PATCH v2 2/2] mac80211: support P2P GO powersave configuration

[Johannes Berg <johannes@xxxxxxxxxxxxxxxx>]

From: Johannes Berg <johannes.berg@xxxxxxxxx>

If the low-level driver wants to support P2P GO
powersave configuration, it must set the cfg80211
flags and mac80211 will pass the parameters to it.
