[PATCH v3 net-next 12/14] dt-bindings: net: dsa: ocelot: add ocelot-ext documentation

[Colin Foster <colin.foster@in-advantage.com>]

The ocelot-ext driver is another sub-device of the Ocelot / Felix driver
system, which currently supports the four internal copper phys.

v3
    * Remove "currently supported" verbage
        The Seville and Felix 9959 all list their supported modes following
        the sentence "The following PHY interface types are supported".
        During V2, I had used "currently supported" to suggest more interface
        modes are around the corner, though this had raised questions.

        The suggestion was to drop the entire sentence. I did leave the
        modified sentence there because it exactly matches the other two
        supported products.

v2
    * New patch

+  VSC7412 (Ocelot-Ext):
+
+    The Ocelot family consists of four devices, the VSC7511, VSC7512, VSC7513,
+    and the VSC7514. The VSC7513 and VSC7514 both have an internal MIPS
+    processor that natively support Linux. Additionally, all four devices
+    support control over external interfaces, SPI and PCIe. The Ocelot-Ext
+    driver is for the external control portion.
