hw/npu2: Setup an error interrupt on some opencapi FIRs
Many errors reported in the NPU FIR2 register, mostly catching unexpected errors on the opencapi link are defined as 'brick fatal' in the workbook, yet the default action is set to system checkstop. It's possible to see those errors during AFU development, where the AFU may send unexpected packets on the link, therefore triggering those errors. Checkstopping the system in this case is clearly extreme, as the error could be contained to the brick and proper analysis of a checkstop is not trivial outside of a bringup environment. This patch changes the default action of those errors so that the NPU will raise an interrupt instead. Follow-up patches will log proper information so that the error can be debugged and linux can catch the event.
