iwlwifi: show current power save status reported by uCode
Power save request is sent from driver to uCode, but there is no indication from uCode about the current device power save state. Reading GP_CNTRL register bit 25:24 to show the current power save status 00: no power save 01: MAC power down 10: PHY power down 11: Error The uCode could switch in and out of power save mode in the order of once per 100-300 ms in many cases. The reading here should just be used for reference on the current uCode power save status. Do not confuse this reading with the PowerSave set by driver and mac80211.
