   InitIrqLevels()

   This function  pre-sets a ll interrupt control registers. It can be used
   to set all interrupt priorities in static applications. If this file
   contains assignments to dedicated resources, verify  that the
   appropriate controller is used.

   NOTE: value 7 disables the interrupt and value 0 sets highest priority.
   NOTE: Two resource interrupts always share one ICR register.
