For all Layerscape platforms, that should be clear, sorry.

We used to the "intr" name for general concept, but no use. So removed.
In the Layerscape platform, the aer and pme interrupt lines are independent, 
not in the Complex Root by MSI or MSIX, so need to read from the DTS before
MSIX and MSI searching for pci service driver.
