net: mdio-ipq4019: Fix the error for an optional regs resource
The second resource is optional which is only provided on the chipset
IPQ5018. But the blamed commit ignores that and if the resource is
not there it just fails.
the resource is used like this,
if (priv->eth_ldo_rdy) {
val = readl(priv->eth_ldo_rdy);
val |= BIT(0);
writel(val, priv->eth_ldo_rdy);
fsleep(IPQ_PHY_SET_DELAY_US);
}
This patch reverts that to still allow the second resource to be optional
because other SoC have the some MDIO controller and doesn't need to
second resource.

net: mdio-mux: Handle -EPROBE_DEFER correctly
When registering mdiobus children, if we get an -EPROBE_DEFER, we shouldn't
ignore it and continue registering the rest of the mdiobus children. This
would permanently prevent the deferring child mdiobus from working instead
of reattempting it in the future. So, if a child mdiobus needs to be
reattempted in the future, defer the entire mdio-mux initialization.
This fixes the issue where PHYs sitting under the mdio-mux aren't
initialized correctly if the PHY's interrupt controller is not yet ready
when the mdio-mux is being probed. Additional context in the link below.
Fixes: 0ca2997d1452 ("netdev/of/phy: Add MDIO bus multiplexer support.")

net: mdiobus: Introduce fwnode_mdiobus_register_phy()
Introduce fwnode_mdiobus_register_phy() to register PHYs on the
mdiobus. From the compatible string, identify whether the PHY is
c45 and based on this create a PHY device instance which is
registered on the mdiobus.
Along with fwnode_mdiobus_register_phy() also introduce
fwnode_find_mii_timestamper() and fwnode_mdiobus_phy_device_register()
since they are needed.
While at it, also use the newly introduced fwnode operation in
of_mdiobus_phy_device_register().
