dt-bindings: ata: ahci-ceva: Cover all 4 iommus entries
[ Upstream commit a7844528722619d2f97740ae5ec747afff18c4be ]
Current only one entry is enabled but IP itself is using 4 different IDs
which are already listed in zynqmp.dtsi.
sata: ahci@fd0c0000 {
compatible = "ceva,ahci-1v84";
...
iommus = <&smmu 0x4c0>, <&smmu 0x4c1>,
<&smmu 0x4c2>, <&smmu 0x4c3>;
};
Fixes: 8ac47837f0e0 ("arm64: dts: zynqmp: Add missing iommu IDs")
