dt-bindings: net: dp83867: Remove binding doc from U-Boot tree

U-Boot is having DT which doesn't cover all options currently supported by
driver. DT binding is aligned with Linux kernel version available here.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ti,dp83867.txt
Based on my talk with Grygorii Strashko better will be to remove it.

Also Linux kernel bindings are being converted to yaml that's another
reason to do it only at one place.

-* Texas Instruments - dp83867 Giga bit ethernet phy
-
-Required properties:
-       - reg - The ID number for the phy, usually a small integer
-       - ti,rx-internal-delay - RGMII Recieve Clock Delay - see dt-bindings/net/ti-dp83867.h
-               for applicable values
-       - ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
-               for applicable values
-       - ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
-               for applicable values
-       - enet-phy-lane-swap - Indicates that PHY will swap the TX/RX lanes to
-               compensate for the board being designed with the lanes swapped.
-       - enet-phy-no-lane-swap - Indicates that PHY will disable swap of the
-               TX/RX lanes.
-       - ti,clk-output-sel - Muxing option for CLK_OUT pin.  See dt-bindings/net/ti-dp83867.h
-                             for applicable values.  The CLK_OUT pin can also
-                             be disabled by this property.  When omitted, the
-                             PHY's default will be left as is.
-
-Default child nodes are standard Ethernet PHY device
-nodes as described in doc/devicetree/bindings/net/ethernet.txt

-Example:
-
-       ethernet-phy@0 {
-               reg = <0>;
-               ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
-               ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
-               ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
-               enet-phy-lane-no-swap;
-               ti,clk-output-sel = <DP83867_CLK_O_SEL_CHN_A_TCLK>;
-       };
