ASoC: rsnd: fixup forever loop bug on SSI
commit
b5b442abd9 ("ASoC: rsnd: add .irq callback")
added .irq support, and it cares both parent SSI and normal SSI.
But it should care only normal SSI. Otherwise SSI might be
forever loop if SSI is used as both parent SSI and normal SSI
(= 2 users), and if under/over run error happen. Because irq disable
do nothing in such case. This patch solve this issue.

It will have TDM settings on SSIWSR. Actually, we would like to set

as clock master (It doesn't need to call rsnd_ssi_config_init() when
clock master mode).

It is nice sense that these all devices are implemented as mod.
DMA will be implemented as module. Then rsnd_dma will be mod base.
This patch makes rsnd_dma mod base, but still not yet completely
finished. This mod is not yet installed to system at this point.

ASoC: rsnd: use common rsnd_ssi_status_xxx()
Current ssi.c driver has random access to SSISR register. Let's use
common rsnd_ssi_status_xxx() function

ASoC: rsnd: avoid pointless loop in rsnd_mod_interrupt()
Current Renesas sound driver doesn't have 1:1 relationship between
stream <-> mod because it is supporting MIX. Because of this reason
rsnd_mod_interrupt() is searching correspond mod by for loop.
But this loop is not needed, because each mod has own type.
This patch avoid pointless loop by using mod->type.
This patch is good for SSI-parent support, because stream might have
2 SSI as SSI-parent/child. SSI interrupt handler will be called twice
if stream has SSI-parent without this patch.

ASoC: rsnd: Don't stop HW even if a large number of errors occur
Current SSI/SRC restarts HW if under/over flow happened to avoid L/R
invert issue. But it will stop HW if too many error happen.
But if it stops on HW, other side under/over flow happen. OTHA, it will
be forever loop interrupt if something strange error happen on
HW/driver without escape route of large number error.
To avoid this issue, it indicates error message if large number error
occur, and disables error interrupt.
