ASoC: fsl_asrc_dma: fix potential null-ptr-deref

dma_request_slave_channel() may return NULL which will lead to
NULL pointer dereference error in 'tmp_chan->private'.

Correct this behaviour by, first, switching from deprecated function
dma_request_slave_channel() to dma_request_chan(). Secondly, enable
sanity check for the resuling value of dma_request_chan().
Also, fix description that follows the enacted changes and that
concerns the use of dma_request_slave_channel().

ASoC: fsl_asrc_dma: fully initialize structs

The driver uses two statically ininitialized struct dma_slave_config,
but only one of them is initialized to zero. Initialize config_be to
zero as well to make sure that no fields are filled with random values.
Let the compiler do this instead of explicitly calling memset() which
makes it easier to read.

dmaengine_terminate_all() is deprecated and should no longer be used.
Use dmaengine_terminate_async() instead. This involves no functional change
since both functions do the same.
After dmaengine_terminate_async() dmaengine_synchronize() must be called
to make sure the channel has really stopped before the underlying memory
is freed. This is done implicitly by dma_release_channel() called from
the .hw_free hook.

ASoC: fsl_asrc_dma: Fix data copying speed issue with EDMA

With EDMA, there is two dma channels can be used for dev_to_dev,
one is from ASRC, one is from another peripheral (ESAI or SAI).

If we select the dma channel of ASRC, there is an issue for ideal
ratio case, the speed of copy data is faster than sample
frequency, because ASRC output data is very fast in ideal ratio
mode.

So it is reasonable to use the dma channel of Back-End peripheral.
then copying speed of DMA is controlled by data consumption
speed in the peripheral FIFO,

The dma channel has been requested by Back-End cpu dai driver already.

there will be below warning with SDMA.

So if we can reuse the dma channel of Back-End, then the issue can be
fixed.

In order to get the dma channel which is already requested in Back-End.
we use the exported two functions (snd_soc_lookup_component_nolocked
and soc_component_to_pcm). If we can get the dma channel, then reuse it,
if can't, then request a new one.

ASoC: fsl_asrc_dma: Fix dma_chan leak when config DMA channel failed

fsl_asrc_dma_hw_params() invokes dma_request_channel() or
fsl_asrc_get_dma_channel(), which returns a reference of the specified
dma_chan object to "pair->dma_chan[dir]" with increased refcnt.

The reference counting issue happens in one exception handling path of
fsl_asrc_dma_hw_params(). When config DMA channel failed for Back-End,
the function forgets to decrease the refcnt increased by
dma_request_channel() or fsl_asrc_get_dma_channel(), causing a refcnt
leak.

Fix this issue by calling dma_release_channel() when config DMA channel
failed.

original sample rate to a common rate supported by Back Ends for playback while
