Xilinx ZynqMP PS PCIe does not report AER interrupts using Advanced
Error Interrupt Message Number. The controller has dedicated interrupt line
for reporting PCIe errors along with AER.
Using dedicated controller irq number for AER which is shared with misc
interrupt handler in pcie-xilinx-nwl. This irq number is set
using PCI quirk.
