Subject: [PATCH v5 1/3] arm/dts: add pcie aer interrupt-name property in the dts

NXP arm 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 patch is intend to fixup the Layerscape platforms which aer
interrupt was not MSI/MSI-X/INTx, but using interrupt line independently.
