[PATCH 4/7] media: sun6i: Don't emit a warning when the configured format isn't found

[Maxime Ripard]

Currently the driver will call WARN when a format isn't available,
resulting in a kernel backtrace in our logs. This makes it look much more
serious than it should be.

Replace the call to the WARN macro to a dev_warn, which will still allow us
to log what happened without making it too dramatic.
