Flush the receive FIFO. There is no specific option for this, we
blindly read bytes and discard them. Reading when there is no data
is harmless. The 8530 has a 4 byte FIFO, the 85230 has 8 bytes.
</p><p>
All locking is handled for the caller. On return data may still be
present if it arrived during the flush.
