iwlwifi: clean up (wowlan) suspend flow
In the WoWLAN suspend flow, instead of accessing registers directly, ask the transport to do the required setup at the end of suspend. If the transport doesn't implement this, don't tell the stack we support WoWLAN. When the device suspends w/o WoWLAN, mac80211 will have stopped it already, which has already called iwl_apm_stop() via stop_hw(). Thus, it isn't necessary to call it again in pcie_suspend and we can simply do nothing there. This unifies the regular and WoWLAN suspend.
