The printk-framework has always expected that when console->write()
returns, the data has been flushed out of the hardware. I am guessing
because it is easiest to avoid possible data loss, for example, due to
suspending hardware.

If you want me to change the current behavior, I can do that in a
separate patch. I would like this patch to only be about fixing the FIFO
timeout issue.
