A user reported failing network with RTL8168dp (a quite rare chip
version). Realtek confirmed that few chip versions suffer from a PLL
power-down hw bug.
Fixes: 07df5bd874f0 ("r8169: power down chip in probe")

Note that since the original change source file r8169.c was renamed
to r8169_main.c. Also the name of the affected functions has changed
from r8168_pll_power_down/up to rtl_pll_power_down/up.
