exynos: spi: Convert the timeout to debug()
Since the timeout is reported through normal channels, and is sometimes expected (e.g. if the bus is being probed for a non-existent device), don't display the message in the driver. In general, drivers should not write to the console as this limits their usefulness in error conditions. Signed-off-by: Simon Glass <sjg@chromium.org>
