r8169: do not enable the TBI for anything but the original 8169.
The TBI bit in PHYStatus is reserved on anything but the oldest 8169. Nobody complained after I disabled it for the 8168 and the 810x (see 66ec5d4fb1ce6f0bd9df4bc4b758f0916d9f37ab). Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Cc: Hayes Wang <hayeswang@realtek.com>
