Current rcar driver is trying to remove kctrl when remove time.
But, 1) rcar driver can't/shouldn't remove before removing sound
card driver, 2) sound card driver will call snd_ctl_dev_free()
and removes all kctrls by snd_ctl_remove().
Thus, rsnd_kctrl_remove() is not necessary. Current implementation
will get Oops when removing rcar driver after sound card.
This patch fix this issue.

IOMMU needs DMA mapping function to use it. One solution is that
we can use DMA mapped dev on snd_pcm_lib_preallocate_pages_for_all()

Current Renesas Sound driver requests DMA channel when .probe timing,
and release it when .remove timing. And use DMA on .start/.stop
But, Audio DMAC power ON was handled when request timing (= .probe),
and power OFF was when release timing (= .remove).
This means Audio DMAC power is always ON during driver was enabled.
To fixup this issue, it should request/release DMA channel on each
playback/recorde timing.
But, DMA channel request/release function uses mutex lock inside.
This means it will breaks current spinlock's interrupt protect.
To solve this issue, DMA channel request/release function needs to
be called from non-spinlock area. This patch adds its callback.

Current SSI is supporting Normal SSI/Multi mode SSI/TDM mode SSI
and its behavior is based on input channels.
This input channel might be converted by CTU,
and SSI needs to be Multi SSI mode / TDM SSI mode if 6ch input
EX) 6ch input, CTU for 2ch, playback
6ch 6ch 2ch 2ch 2ch 2ch
-> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI
EX) 6ch input, no CTU, Multi SSI, playback
6ch 6ch 6ch 6ch 6ch 2ch
-> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI0/SSI1/SSI2
Current driver is using rsnd_get_adinr_chan() / rsnd_get_slot_width()
for this purpose, but it is complicated enough without meaning.

SSI will be used as normal SSI or as clock parent SSI. Therefor,
rsnd driver wants to control SSI and parent SSI separately. Otherwise it
can't use Playback/Capture in the same time.
And it has been done by c2dc47d5cf("ASoC: rsnd: rsnd_dai_stream has each
mod's status insted of rsnd_mod") before.
OTOH, rsnd driver doesn't want to control CTU/MUX/DVC/SSIU/SSI in
separately. Otherwise, these will be re-initialized during playing if
MUX merges 2 sounds.
Because of these picky reasons, this patch re-defines status on each mod,

Currently the number of DAI links is statically defined by the machine
driver at build time using an array. This makes it difficult to shrink/
grow the number of DAI links at runtime in order to reflect any changes
in topology.
We can change the DAI link array in the core to a list so that PCMs and
FE DAI links can be added and deleted at runtime to reflect changes in
use case and DSP topology. The machine driver can still register DAI links
as an array.
As the 1st step, this patch change the PCM runtime array to a list. A new
PCM runtime is added to the list when a DAI link is bound successfully.
Later patches will further implement the DAI link list.
More:
- define snd_soc_new/free_pcm_runtime() to create/free a runtime.
- define soc_add_pcm_runtime() to add a runtime to the rtd list.
- define soc_remove_pcm_runtimes() to clean up the runtime list.
- traverse the rtd list to probe the link components and dais.
- Add a field "num" to PCM runtime struct, used to specify the device
number when creating the pcm device, and for a soc card to access
its dai_props array.
- The following 3rd party machine/platform drivers iterate the rtd list
to check the runtimes:
sound/soc/intel/atom/sst-mfld-platform-pcm.c
sound/soc/intel/boards/cht_bsw_rt5645.c
