audio_device: Update explicit feedback support

2020-09-28T06:41:17Z

Feedback can be specified by the user code and will be sent at feedback endpoint specified interval.

audio_device: Allow one FIFO for N channels

2020-09-28T06:41:17Z

This allow to build with single FIFO for devices with multiple channels. Having just one FIFO greatly reduces time needed to feed endpoint. This change also allows to have one FIFO with 24 bit samples that is not rounded up to 32 bit elements. CFG_TUD_AUDIO_RX_ITEMSIZE and CFG_TUD_AUDIO_TX_ITEMSIZE can be manually defined. This allows to use FIFO more efficiently when 24 bits samples are already using 3 bytes, in this case there is no need to put them into FIFO one by one. For 8, 16, 32 bits samples size efficient FIFO access is always used when single FIFO is selected. This also changes FIFO element size to 1, FIFO usage was confusing in some place it treated content as byte base in other it looked like ITEM size is to be used. Also bufsize that in most (maybe all) cases was really meaning item count. bufsize now mean buffer size in bytes so there is no confusion.

audio_device: Fix tud_audio_n_read_flush TU_VERIFY usage

2020-09-28T06:41:17Z

void function used TU_VERIFY in a way that returned bool value. It would not compile.

audio_device: Fix audio_rx_done_type_I_pcm_ff_cb bufor size check

2020-09-28T06:41:17Z

Function was not checking buffer size correctly due missing parenthesis.

audio_device: Fix audio_rx_done_type_I_pcm_ff_cb prototype

2020-09-28T06:41:17Z

Function prototype did not have return type specified by mistake.
