This commit organizes all possible register parameter lists in a map.

This is so findRegister can search each register map from a single data structure
instead of having to hardcode every new register parameter list in the findRegister function.

Now, to add a new register, developer should only need to:

  1 - Create the register parameter list and add it to the map in vmm_tbl.h:39-41
  2 - ... I think that's it(?)

Also, asynPrint should tell which hybrid, vmm and register are being affected by the operation now.
