The src_maxburst and dst_maxburst means the watermark level for
p2p, no need to be scaled.

When ASRC P2P is working, it will check the xrun status of cpu dai
in the back end bistream. then will do Whole route stop and restart.

When using ASRC p2p as a for-end with other back-end modules like ESAI,
it'd be safer to add 1ms delay, less might be futile for extreme cases,
after enabling ASRC so as to keep ASRC output FIFO with enough data to
content the DMA burstsize of back-ends and accordingly prevent underrun
that might happen to them.

Each CPU DAI driver has its own defined DMA buffer size, so this patch just
drops the original one that uses a fixed size for all drivers and implements
a different DMA buffer size to each driver.

ASRC and HDMI audio might meet unexpected stop, 'ctrl+z' for example,
and then disable its sdma channel. But after 'fg' resume, because sdma
channel's status has already been set into DMA_ERROR, we need to prepare
dmaengine again to clear its error state, otherwise sdma driver would
bypass its channel enabling and 'Input/Output error' would happen to
ALSA lib.
The combined prepare and submit are also being used in soc-dmaengine,
the common ASoC dmaengine driver.
And since we already use a proper way to handle sdma channel status,
there's no need to make an exception for HDMI any more, so drop it.
