* Name: board_i2sdev_initialize
*
* Description:
* This function is called by platform-specific, setup logic to configure
* and register the generic I2S audio driver. This function will register
* the driver as /dev/audio/pcm[x] where x is determined by the I2S port
* number.
*
* Input Parameters:
* port - The I2S port used for the device
* enable_tx - Register device as TX if true
* enable_rx - Register device as RX if true
*
* Returned Value:
* Zero is returned on success. Otherwise, a negated errno value is
* returned to indicate the nature of the failure.
