net: Implement random ethaddr fallback in eth.c
Implement the random ethaddr fallback in eth.c so it is in a common place and not reimplemented in each board or driver that wants this behavior. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

environment variable will be used unchanged.
If the environment variable is not set, it will be initialized from
eth_device->enetaddr, and a warning will be printed.
+ If both are invalid and CONFIG_NET_RANDOM_ETHADDR is defined, a random,
+ locally-assigned MAC is written to eth_device->enetaddr.
4. Program the address into hardware if the following conditions are met:
a) The relevant driver has a 'write_addr' function
b) The user hasn't set an 'ethmacskip' environment variable
