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.
