I _think_ it can be simpler:

int fwnode_mdiobus_phy_device_register(struct mii_bus *mdio,
				       struct phy_device *phy,
				       struct fwnode_handle *child, u32 addr)
{
	int rc;

	rc = fwnode_irq_get(child, 0);
	/* Don't wait forever if the IRQ provider doesn't become available,
	 * just fall back to poll mode
	 */
	if (rc == -EPROBE_DEFER)
		rc = driver_deferred_probe_check_state(&phy->mdio.dev);
	if (rc == -EPROBE_DEFER)
		return rc;

	if (rc > 0) {
		phy->irq = rc;
		mdio->irq[addr] = rc;
	} else {
		phy->irq = mdio->irq[addr];
	}

So if there was an interrupt in DT, mdio->irq[addr] has been set to
it. So all i think you need is

    phydev->irq = mdio->irq[addr];

And a comment.
