An older version of the databook said to wait for the FIFO to drain,
but that has been removed from the newer databooks. The Synopsys driver
used to have that code, but it caused problems when testing against one
of the hosts that are available in the market. I talked to one of the
RTL engineers, and he said we should not do the wait.
