@brief Reconfigure the I2S slot for PDM RX mode @note Only allowed to be called when the channel state is READY, i.e., channel has been initialized, but not started this function won’t change the state. i2s_channel_disable should be called before calling this function if I2S has started. @note The input channel handle has to be initialized to PDM RX mode, i.e., i2s_channel_init_pdm_rx_mode has been called before reconfiguring

@param[in] handle I2S RX channel handler @param[in] slot_cfg PDM RX mode slot configuration, can be generated by I2S_PDM_RX_SLOT_DEFAULT_CONFIG @return - ESP_OK Set clock successfully - ESP_ERR_NO_MEM No memory for DMA buffer - ESP_ERR_INVALID_ARG NULL pointer, invalid configuration or not PDM mode - ESP_ERR_INVALID_STATE This channel is not initialized or not stopped
