Power domain driver sends PM fragment to PMUFW. It is sent for every node
which is listed in DT. But some nodes could be already enabled but driver
is not capable to find it out. That's why it blinly sents request for every
listed IP. When PMUFW response by XST_PM_ALREADY_CONFIGURED error code
there is no need to show any error message because node is already enabled.
That's why cover this case with message when DEBUG is enabled.

For configurations with gmii2rgmii and external phy the DT nodes link
should be gem->gmii2rgmii->phy. But due to limitation in Linux driver
the DT is mentioned as gem->phy and gmii2rgmii->phy as shown in below DT.

phy-handle = <0x0e>;

};
};
};
Since same DT is used in Linux and U-Boot we need to workaround this
issue by using the gmii2rgmii node which points to phy and we should
ignore the gem pointing to phy directly.
Do this workaround by updating priv->phydev->node value with
priv->phy_of_node only if it is not valid node.

Perform reset before core initialization.
Standard flow which close to 99% users are using getting all IPs out of
reset that there is no need to reset IP again. This is because of all low
level initialization is done in previous bootloader stage.
In SOM case these IPs are not touched by previous bootloader stage that's
why reset needs to be called before IP is accessed to make sure that it is
in correct state.

Xilinx DTS files are using two way how to describe ethernet phy.
The first (already supported) has phy as subnode of gem node.
eth {
phy-handle = <&phy0>;
phy0: ethernet-phy@21 {
...
};
};
The second has mdio subnode (with mdio name) which has phy subnode. This
structure allow hadling MDIO reset signal (based on Linux mdio.yaml)
eth {
phy-handle = <&phy0>;
mdio {
phy0: ethernet-phy@21 {
...
};
};
};
This patch adds support for the second case where mdio subnode
is found driver will look at its parent to find out which gem is handling
MDIO bus.
