dahdi: Fixed loopup/loopdown signals
The loopup/loopdown T1 maintenance feature in the single through quad-span
drivers now function properly, according to AT&T TR54016, by sending a
full rate pattern down the line. T1.403 ESF/Data Link patterns are not
supported currently.
Also grouped all the maint reset register clears under a single irq lock
to crank the performance up past 11.
