Add device-tree binding documentation SFP transceivers. Support for SFP
transceivers has been recently introduced (drivers/net/phy/sfp.c).

v2:
    Rename -gpio properties to -gpios
    Rename the rate-select-gpio property to rate-select0-gpios
    Add the rate-select1-gpios property
    Add examples

+- i2c-bus : phandle of an I2C bus controller for the SFP two wire serial

+- moddef0-gpios : phandle of the MOD-DEF0 (AKA Mod_ABS) module presence input
+  gpio signal

    Your example shows there's GPIO phandle *and* specifier.

Would "GPIO specifier" be enough here?

    No, specifier is the cells following GPIO (or any other) phandle.
