[arm-allstar] Urix Pin 9

[Larry]

Thanks Doug,

I wondered about that. The schematic looked like originally it might 
have went to where the MIC_AC goes and was later edited to use pin 21. 
Labeling in that area on the schematic was a bit confusing and I could 
find no termination for it on the CM11 chip. I thought it might have 
been abandoned and be an open pin afterwards.  Appreciate the feedback.
