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@fd0c0000 {
	compatible = "ceva,ahci-1v84";
	...
	iommus = <&smmu 0x4c0>, <&smmu 0x4c1>,
		 <&smmu 0x4c2>, <&smmu 0x4c3>;
};
