z8530_flush_fifo - Flush on chip RX FIFO
void z8530_flush_fifo (struct z8530_channel * c);
c Channel to flush
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.
All locking is handled for the caller. On return data may still be
present if it arrived during the flush.
