Both the v6 qca8k series and the separate ipq806x mdio series, yes?

There's definitely something odd going on here. I went back to mainline
to see what the situation is there. With the GPIO MDIO driver both
switches work (expected, as this is what I run with). I changed switch0
over to use the IPQ MDIO driver and it wasn't detected (but switch1
still on the GPIO MDIO driver was fine).
I then tried putting both switches onto the IPQ MDIO driver and in that
instance switch0 came up fine, while switch1 wasn't detected.
If there's a simple patch that might give more debug I can try it out.
