i2c-designware: i2c_dw_func: Set I2C_FUNC_SMBUS_foo bits
Set proper I2C_FUNC_SMBUS_* bits so that the driver could be used with some utilities requiring SMBus functionalities, such as i2c-tools. Note that DW I2C core doesn't support I2C_FUNC_SMBUS_QUICK, as it's not capable of zero-length data transactions.
