i2c: add binding to mark a bus as supporting SMBus-Alert
Since SMBus-Alert is an optional feature of SMBUS which
requires an additional pin, the smbus binding cannot be
used to indicate its support.
Add an additional smbus-alert binding specific for it and
update the description text of smbus to avoid mentioning
SMBus-Alert
