[DistroKit] [PATCH] v8a: barebox: derive stable MAC address from machine ID

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The i.MX ocotp driver already registers the SoC serial number, so
it can be hashed into a machine ID. barebox can also derive a MAC
address this way, so enable that option, so boards that have no
proper MAC address fused get assigned a MAC address that stays
constant over reboots.
