Subject: [PATCH] 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.
