sandbox: Allow the console to work earlier

With sandbox, errors and problems may be reported before console_init_f()
is executed. For example, an argument may not parse correctly or U-Boot may
panic(). At present this output is swallowed so there is no indication what
is going wrong.

Adjust the console to deal with a very early sandbox setup, by detecting that
there is no global_data yet, and calling os functions in that case.
