IOW: The fixup unregistering functions are unused and can be removed. Remove also documentation for these functions. Whilst at it, remove also mentioning of phy_register_fixup() from the Documentation, as this function has been static since ea47e70e476f ("net: phy: remove fixup-related definitions from phy.h which are not used outside phylib"). Fixup unregistering functions were added with f38e7a32ee4f ("phy: add phy fixup unregister functions") in 2016, and last user was removed with 6782d06a47ad ("net: usb: lan78xx: Remove KSZ9031 PHY fixup") in 2024.
