Is all this guaranteed to be the same between different boards?
No, this looks like a total subsystem overreach, these should be
taken care of from within clk framework and consumed with the clk
APIs.

There are patches for QCA8084 clocks:
https://patchwork.kernel.org/project/linux-arm-msm/cover/20231104034858.9159-1-quic_luoj@xxxxxxxxxxx/
I guess all of the clocking should be done there, it isn't really a MDIO issue.

Thanks Robert for the link of this patch.
Yes, the clock driver of qca8084 is probed as the MDIO device, the
configuration sequence here to lighten the qca8084 PHY need to
be completed before the clock APIs available to call.
