i2c: i2c-smbus: Move i2c_setup_smbus_alert from i2c-smbus to i2c-core-smbus
In preparation to adding of_i2c_setup_smbus_alert() move i2c_setup_smbus_alert() to core module. of_i2c_setup_smbus_alert() will call i2c_setup_smbus_alert() and this avoid module dependecy issues. Signed-off-by: Phil Reid <preid@electromag.com.au> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
