drivers/r8168: Read default MAC address from CBFS

This driver applies to 10ec:8168

Previously, this driver resetted the nic and set a hardcoded
    MAC address.  Now the driver reads a default MAC address
    from CBFS in the form of a string:
    echo -n "xx:xx:xx:xx:xx:xx" > macaddress
    and store the macaddress file in CBFS with the same name.

TESTED on GA-G41M-ES2L and GA-945GCM-S2L:
           MAC address was detected
