Data done irq is expected if data length is less than watermark in PIO mode. But fifo watermark is requested to be aligned with data length in some SoC so that TX/RX irq can be generated with data done irq. Add the watermark alignment to mark this requirement and force fifo watermark setting accordingly. Signed-off-by:
