On some boards, a MAC address is set based on the CPU ID or other
information. This is usually done in the misc_init_r() function.
This becomes a problem for net devices that are probed after the call to
misc_init_r(), for example, when the ethernet is on a PCI port, which
needs to be enumerated.
In this case, misc_init_r() will set the ethaddr variable, then, when
the ethernet device is probed, if it has a ROM address, u-boot will warn
about a MAC address mismatch and use the misc_init_r() address instead
of the one in ROM.
The operating system later will most likely use the ROM MAC address,
which can be confusing.
To avoid that, this commit introduces NET_PREFER_ROM_MAC_ADDR that can
be set for boards that have such an interface.

Won't the system pick ROM MAC if $ethaddr is not set ?
