The invalid value of #address-cells in the imx6 pcie host controller node
causes of_irq_parse_raw() to incorrectly advance through an interrupt-map
table of more than one interrupt.
This patch resolves this issue and allows proper interrupt mapping for an
imx6 pcie host connected to a P2P bridge when using legacy interrupts.
