inject-vm-err: T19x MC error handler

- Add support to handle Memory Controller errors on
  on t19x.
- This change adds a sample handler for MC errors.
  It is a minimal handler that just dumps error
  information to the console. This can be used as
  a reference to implement an elaborate error
  handler.
