The workaround enabled by CONFIG_MPIC_BROKEN_REGREAD does not work on non-broken MPICs. The symptom is no interrupts being received. The fix is twofold. Firstly the code was broken for multiple isus, we need to index into the shadow array with the src_no, not the idx. Secondly, we always do the read, but only use the VECPRI_MASK and VECPRI_ACTIVITY bits from the hardware, the rest of "val" comes from the shadow.
