[PATCH 3/7] media: sun6i: Pass the sun6i_csi_dev pointer to our helpers

[Maxime Ripard <maxime.ripard@xxxxxxxxxxx>]

Some helpers need to log some errors for example when we don't support the
format passed as an argument. However, we don't currently have a dev
pointer available in those functions, preventing us from using any dev_*
logging function.

Fix that by passing the sun6i_csi_dev structure as an argument, which
itself contains a pointer to our struct device.
