wl12xx: set the ELP entry delay to the FW dyn-ps timeout
With PSM handled in FW, the checks in wl1271_elp_work() are always true. Thus during active traffic we constantly enter and exit ELP (many times per second). As each ELP exit takes ~10ms, this can have an adverse effect on throughput and interactivity. Set the ELP timeout to the dyn-ps timeout. This period is longer and avoids the above problem. It also makes sense to stay out of ELP while we are awake on the network, to minimize delays in Tx/Rx. The same thing was done by the mac80211 dynamic-ps mechanism before the FW DPS changes.
