* Name: I2CS_SETFREQUENCY
*
* Description:
* Set the I2C frequency. This frequency will be retained in the struct
* i2c_slave_s instance and will be used with all transfers. Required.
*
* Input Parameters:
* dev - Device-specific state data
* frequency - The I2C frequency requested
*
* Returned Value:
* Returns the actual frequency selected
*
