@brief Get I2C master clock period

@param i2c_num I2C port number @param high_period pointer to get clock cycle number during SCL is high level, will get a 14 bit value @param low_period pointer to get clock cycle number during SCL is low level, will get a 14 bit value

@return - ESP_OK Success - ESP_ERR_INVALID_ARG Parameter error
