Subject: [PATCH] sh: ap325 camera without i2c driver fix

This patch fixes the ap325rxa ncm03j camera code to handle
the case where no i2c driver is present. Without this fix
i2c_transfer() may be passed NULL as adapter which results
in a crash.

Triggered when i2c-sh_mobile.c failed to probe() due to
missing MSTP clocks.
