commit d644122d8420c425fdf5c74e50d440d5f146bc0c

    ARM: dts: imx: fix invalid #address-cells value
    
    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. We also take the opportunity to drop the
    unused #size-cells here.
    
    This patch resolves this issue and allows proper interrupt mapping for an
    imx6 pcie host connected to a P2P bridge when using legacy interrupts.
