Documentation: net-sysfs: Remove duplicate PHY device documentation
Both sysfs-bus-mdio and sysfs-class-net-phydev contain the same duplication information. There is not currently any MDIO bus specific attribute, but there are PHY device (struct phy_device) specific attributes. Use the more precise description from sysfs-bus-mdio and carry that over to sysfs-class-net-phydev.

- Boolean value indicating whether the PHY device has
- any fixups registered against it (phy_register_fixup)
+ This attribute contains the boolean value whether a given PHY
+ device has had any "fixup" workaround running on it, encoded as
