Subject[PATCH v5] net: ethernet: nb8800: support fixed-link DT node

Under some circumstances, for example when connecting
to a switch:

https://stackoverflow.com/questions/31046172/device-tree-for-phy-less-connection-to-a-dsa-switch

the ethernet port will not be connected to a PHY.
In that case a "fixed-link" DT node can be used to replace it.

This patch adds support for the "fixed-link" node to the
nb8800 driver.
