[U-Boot] [PATCH v3 03/14] Revert "sandbox: Drop special case console code for sandbox"

While sandbox works OK without the special-case code, it does result in
console output being stored in the pre-console buffer while sandbox starts
up. If there is a crash or a problem then there is no indication of what
is going on.
For ease of debugging it seems better to revert this change also.
This reverts commit d8c6fb8cedbc35eee27730a7fa544e499b3c81cc.
