u-boot-mvebu: set configuration options in Makefile

CONFIG_* variables can easily be set by overriding Build/Configure.
so set NET_RANDOM_ETHADDR=y and CMD_SETEXPR=y here.

This replaces the following patches:
0001-clearfog-generate-random-MAC-address.patch
0004-clearfog-enable-setexpr-command-by-default.patch

-
-The Clearfog does not come with predetermined MACs.
-Falling back to random ones ensures ethernet can still operate anyway.
