[PATCH v6 2/3] arm64/dts-ls1043-ls2080: add pcie aer/pme interrupt-name property in the dts

Some platforms(NXP Layerscape for example) aer/pme interrupts was not
MSI/MSI-X/INTx but using interrupt line independently. This patch
add "aer", "pme" interrupt-names for aer/pme interrupt.

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

Since the interrupt-names "intr" never been used. Remove it.

changes for v6:
	- add remove "intr" interrupt reason.
	- add "pme" interrupt.
