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 forces a realtek 10ec:8168 card to reset to ensure power state
is correct at boot.

help
This is a string to set the mac address on a Realtek rt8168 card.
It must be in the form of "xx:xx:xx:xx:xx:xx", where x is a
hexadecimal number for it to be valid. Failing to do so will
result in the default macaddress being used.
