   TX3927 has three channel timer of which only channel 0 is used to 
implement a clocksource -- however, clocksource code whould also need to be 
changed since it's now jiffy-based and HRT doesn't tolerate this -- of course, 
if anybody still cared about this boards

   Here we have a case of a vendor abusing the count/compare register and 
also adding 3 more of them. One pair can be used for clockevents, the other 
for clocksource (its compare reg. being programmed to all ones).
