[PATCH v4 1/2] nxp/dts: add pcie aer interrupt-name property in the dts

NXP some platforms aer interrupt was not MSI/MSI-X/INTx
but using interrupt line independently. This patch add a "aer"
interrupt-names for aer interrupt.
With the interrupt-names "aer", code could probe aer interrupt
line for pcie root port, replace the aer interrupt service irq.
This is intend to fixup the Layerscape platforms which aer interrupt
was not MSI/MSI-X/INTx, but using interrupt line independently.
