* Name: esp32s3_es8311_initialize
*
* Description:
* This function is called by platform-specific, setup logic to configure
* and register the ES8311 device. This function will register the driver
* as /dev/audio/pcm[x] where x is determined by the I2S port number.
*
* Input Parameters:
* i2c_port - The I2C port used for the device
* i2c_addr - The I2C address used by the device
* i2c_freq - The I2C frequency used for the device
* i2s_port - The I2S port used for the device
*
* Returned Value:
* Zero is returned on success. Otherwise, a negated errno value is
* returned to indicate the nature of the failure.
