[PATCH v11 02/10] i2c: i2c-smbus: Move i2c_setup_smbus_alert from i2c-smbus to i2c-core-smbus

[Phil Reid <preid-qgqNFa1JUf/o2iN0hyhwsIdd74u8MsAO@public.gmane.org>]

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.
