Set up some hardware registers and creates interrupt service routines for the doorbells and messages.
There are 64 doorbells in the switch that are shared between all partitions. The upper 4 doorbells are also shared with the messages and are therefore not used. Thus, this provides 28 doorbells for each partition.
