I found there is patch which adds unit address, so I think we need @0 here.
commit 951c1d37f691027f149bbc58bbf0c207450a3654
Author: Fabio Estevam <festevam@...il.com>

    arm64: dts: imx8mm: Pass a unit name for the 'soc' node

    The 'soc' name needs a unit name to match its 'ranges' property.

    Pass the unit name in order to fix the following dtc build warning
    with W=1:

    arch/arm64/boot/dts/freescale/imx8mm.dtsi:203.6-754.4: Warning (unit_address_vs_reg): /soc: node has a reg or ranges property, but no unit name

    This also aligns with imx8mq.dtsi.

There is two iomuxc, one is for M33, one is for A35.
Similar with i.MX7ULP,  we use a suffix here.
