Subject: [PATCH v2] dt-bindings: ata: ahci-ceva: Cover all 4 iommus entries

Current only one entry is enabled but IP itself is using 4 different IDs
which are already listed in zynqmp.dtsi.

sata: ahci@...c0000 {
	compatible = "ceva,ahci-1v84";
	...
	iommus = <&smmu 0x4c0>, <&smmu 0x4c1>,
		 <&smmu 0x4c2>, <&smmu 0x4c3>;
};

Fixes: 8ac47837f0e0 ("arm64: dts: zynqmp: Add missing iommu IDs")
Cc: stable@...r.kernel.org # v5.12+
