configs: aspeed: Add HUSH and random ethernet addr

Tests in test/py/tests/test_env.py like this fail without CONFIG_HUSH_PARSER:

 => => printenv test_env_0
 ## Error: "test_env_0" not defined
 => .=> setenv test_env_0
 => => echo $test_env_0
 $test_env_0
 => F

We also want a mac address so the ethernet device works in qemu.
