Documentation: devicetree: Add PHY no lane swap binding



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
		bootstrap configuration caused by issues in PCB layout design.
