r8169: PHY power-on fix
Fix extracted from Realtek's driver (8.002.00/20070713) for the PHY
attached to 8111/8168b chipsets.
The check against mac_version is just usual paranoia during the bugfix
period of the kernel cycle. -- FR
Tested on Asus M2A-VM motherboard by Roger So.
No regression on my Asrock 945G DVI either (built-in 8168 + 2x8169).
