[U-Boot] [PATCH 02/13] Revert "sandbox: Drop special case console code for sandbox"

[Simon Glass]

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.
