DPU interrupts code allows multiple callbacks per interrut. In reality
/interrupt
none of the interrupts is shared between blocks (and will probably
never
be). Drop support for registering multiple callbacks per interrupt to
simplify interrupt handling code.

I need to check on why we had this design originally and we still do.
the idx with which we are registering today can generate only one hw
interrupt.
But i am not sure if something for planned for future use. Will update
in a day or two.
meanwhile some comments and questions below.
