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).
