NXP arm aer/pme interrupts was not MSI/MSI-X/INTx but using interrupt
line independently. This patch add a "aer" "pme" interrupt-names for
aer/pme interrupts.
With the interrupt-names "aer","pme" code could probe aer/pme interrupt
line for pcie root port, replace the aer/pme interrupt service irqs.
This patch is intend to fixup the Layerscape platforms which aer/pme
interrupt was not MSI/MSI-X/INTx, but using interrupt line independently.
Since the interrupt-names "intr" never been used. Remove it.
