Convert the bindings for socfpga-dwmac to yaml. Since the original

Did you test this against your dts files?:

ethernet@ff804000 (altr,socfpga-stmmac-a10-s10): iommus: [[11, 3]] is too short
ethernet@ff802000 (altr,socfpga-stmmac-a10-s10): iommus: [[11, 2]] is too short
ethernet@ff800000 (altr,socfpga-stmmac-a10-s10): iommus: [[11, 1]] is too short

There's also one for 'phy-addr', but that needs to be dropped from the
.dts files as it doesn't appear to be used.

[...]

+  iommus:
+    maxItems: 2

You need to add:

minItems: 1
