[RFC v2 1/3] i2c: smbus: move of_i2c_setup_smbus_alert declaration to i2c-core.h

[Phil Reid <preid@electromag.com.au>]

This declaration isn't used by anything outside of the i2c-core at
present. In preparation for moving the smbus_alert code from it's
own module into the i2c-core move to i2c-core.h
