Add the documentation to avoid PHY lane swapping. This is a boolean
entry to notify the phy device drivers that the TX/RX lanes NO need
to be swapped.
The use case for this binding mostly happens after wrong HW
configuration of PHY IC during bootstrap.

- enet-phy-lane-swap: If set, indicates the PHY will swap the TX/RX lanes to
compensate for the board being designed with the lanes swapped.
+- enet-phy-lane-no-swap: If set, indicates that PHY will disable swap of the
+ TX/RX lanes. This property allows the PHY to work correcly after e.g. wrong

Ah! O.K. Something odd going on with the threading of the patches. 1/3
seems to be last!
