Luiz Angelo Daros de Luca 0263cb3835 kernel: netdevices: add realtek DSA modules
Uses upstream DSA switch modules (rtl8365mb, rtl8366), similar to
RTL8367C and rtl8366rb swconfig drivers.

The package dependencies exclude targets built without kernel CONFIG_OF.

It also fixes the rtl8366rb LED support.

Subject: net: dsa: realtek: get internal MDIO node by name
The binding docs requires for SMI-connected devices that the switch
must have a child node named "mdio" and with a compatible string of
"realtek,smi-mdio". Meanwile, for MDIO-connected switches, the binding
docs only requires a child node named "mdio".
This patch changes the driver to use the common denominator for both
interfaces, looking for the MDIO node by name, ignoring the compatible
string.
