PrPMC800 interrupt problem

A better solution is perhaps to change openpic_init from

	if (NumSources == 0)
		openpic_set_sources(0,
				    ((t & OPENPIC_FEATURE_LAST_SOURCE_MASK) >>
				     OPENPIC_FEATURE_LAST_SOURCE_SHIFT) + 1,
				    NULL);

to

	if (NumSources == 0) {
   		int irqs;
	    irqs = ((t & OPENPIC_FEATURE_LAST_SOURCE_MASK) >>
				     OPENPIC_FEATURE_LAST_SOURCE_SHIFT) + 1;
	    if (irqs < OpenPIC_NumInitSenses) {
	      // Some internal interrupt is defined, init it's vector as well
		  irqs = OpenPIC_NumInitSenses;
        }
		openpic_set_sources(0, irqs, NULL);
     }

Any insight is welcome! As far as I can see, open_pic.c does not handle
timer, ipi, uart or any other internal interrupt sources (as they are not
reported in the feature register).
