Currently, camnoc buffer fill level register offsets are part of cpas monitoring. Register offsets keep changing between targets which would bring more conditionals. Make cpas monitoring generic by moving register offsets to header. Also, the reg values will be read in a buffer, and it can be controlled what offset needs to be read, by changing status in header to be enable/disable. Also, move camnoc fill level printing to CPAS for when we need only buffer fill info.
