drivers/net/rt8168: Add a macaddress cbfsfile using Kconfig
The default macaddress in rt8168.c can be changed with a cbfsfile called macaddress. This patch makes it possible to add such a file using Kconfig at build time. This also changes the name of the cbfsfile from "macaddress" to "rt8168-macaddress" to avoid confusion.

+ This is a string to set the mac address on a Realtek rt8168 card.
