    IRQ index changes:
    ad4170_asdz
    * $hier_spi_engine 11 -> 12

    ad57xx_ardz
    * ad57xx_dma 12 -> 13
    * $hier_spi_engine 11 -> 12

    cn0579
    * cn0579_dma 13 -> 12
    * axi_iic_ard 12 -> 11

    cn0540
    * $hier_spi_engine 11 -> 12
    * axi_iic_cn0540   12 -> 11

On linux, some rework to the cora dtsi is required to load the fpga axi as an overlay, since we will defer loading the bitsream moving forward.
And existing merged dts?
