This should fix the too short dwell time problem which prevented some of the probe requests from being transmitted in cases of high number of SSIDs (10+) to be actively sched scanned. However, in the common case of having up to 1-2 SSIDs that require active scan, the dwell time would be kept to a minimum which should conserve power.

Move some common register values from wl12xx to wlcore and add the registers table to wl12xx.
