Vybrid security issue, resetting things

I having some issues with a few devices that I believe that some security bits got set and are preventing the device from operating correctly.  The issue is that the SNVS_HPRTCLR register doesn't increment anymore.  This code has worked for years and it stopped one day.  I do see that the PGD bit in the SNVS_LPSR is set.  There are probably others as well.  I believe something happened where the chip thought there was some sort of tampering going on and shut some stuff off.  Also this problem is only happening on a couple of my devices.  The rest work just fine.
