With such configuration I see IPMMU related logs. From the following string "(XEN) I/O virtualisation disabled" in your log, I assume that IPMMU hasn't been registered. Probably, you have IPMMU devices disabled/removed in your host device-tree and Xen couldn't pick them up. If this is a reason, then you need to enable them ("IPMMU root" device and required "IPMMU cache(s)") and tie required bus masters (DMA devices) to "IPMMU caches".
For example, H3 case:
/* root */
&ipmmu_mm {
status = "okay";
};
/* cache */
&ipmmu_ds0 {
status = "okay";
};
/* DMA device */
&avb {
iommus = <&ipmmu_ds0 16>;
};
