Current simple-card returns error if DAI doesn't
support .set_fmt callback.
But the error is -ENOTSUPP (= not supported),
and it is not error.
This patch avoids such case

The conversion of the si476x to regmap removed locking of the core during
register updates, allowing things like power state changes for the MFD to
happen during a register update. Avoid this by taking the core lock in the
DAI operations (which are the only things that do register updates) as we
used to do in the open coded register I/O functions.

The current si476x I/O implementation wraps the regmap for the core with
functions that make the register map cache only when the device is powered
down. This implementation appears to be incomplete since there is no code
to synchronise the cache so writes done while the core is powered down
will be ignored, the device will only be configured if it is powered.
A better and more idiomatic approach would be to have the MFD manage the
cache, making the device cache only when it powers things down. This also
allows ASoC to use the standard regmap helpers for the device which helps
remove the ASoC custom ones so do convert to do that.

There is no need for the CODEC to go to standby on resume since the core will
power it up as needed and in any case it is an idle_bias_off CODEC so would
normally sit with bias off while idle.

If we have control over the LDO then disable it during suspend; the device
is already being put into reset so will be non-functional over suspend
anyway and this will save a small amount of power.

The ACPI_PTR() macro evaluates to NULL if ACPI is disabled and hence the
ACPI match table won't be used, causing the compiler to complain. Avoid
this by protecting the table using an #ifdef CONFIG_ACPI.

R-Car sound has clock pin for each SSI, and sometimes,
these pins are shared with paired SSI.
It may sometimes become "SSI-A clock pin is master" and
"SSI-B clock pin is slave", but "SSI-A/B clock pins are shared".
SSI-B needs SSI-A clock in this case.
Current R-Car sound driver is using RSND_SSI_xxx flag
to control this kind of shared pin behavior.
But, this information, especially clock master setting,
can be got from ASoC set_fmt settings.
This patch removes rsnd_ssi_mode_init() and extend rsnd_ssi_mode_set()
to controlling pin settings via .set_fmt.
This patch doesn't removes RSND_SSI_CLK_FROM_ADG flag at this point
to avoid conflict branch merging between ASoC <-> SH-ARM.

And SCU needs RSND_SCU_USE_HPBIF flag
to decide HPBIF is enable/disable.
But these 2 means same things.
This patch adds new rsnd_scu_hpbif_is_enable()
function, and merges above methods.

Current Linux kernel is supporting regmap_field method
and it is very useful feature.
It needs one regmap_filed for one register access.
OTOH, there is multi port device which
has many same registers in the market.
The difference for each register access is
only its address offset.
Current API needs many regmap_field for such device,
but it is not good.
This patch adds new regmap_fileds API which can care
about multi port/offset access via regmap.

PXA25x also shows some problems when using interrupts during reset

ready state). Instead use a common mdelay-loop on all platforms to
detect codecs becoming ready.
