ASoC: fsl: Convert to RUNTIME_PM_OPS() and co
Use the newer RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros
instead of SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() together
with pm_ptr()

This optimizes slightly when CONFIG_PM is disabled, too.

ASoC: fsl_micfil: Add decimation filter bypass mode support
When decimation filter bypass mode is enabled, PDM data can be
written into FIFO directly without any processing.

The interface of this mode is DSD big endian format, when
user needs this format, then this mode is enabled.

This mode is only for the i.MX943 platform currently.

ASoC: fsl_micfil: Enable default case in micfil_set_quality()
If 'micfil->quality' received from micfil_quality_set() somehow ends
up with an unpredictable value, switch() operator will fail to
initialize local variable qsel before regmap_update_bits() tries
to utilize it.

While it is unlikely, play it safe and enable a default case that
returns -EINVAL error.

analysis tool SVACE.

ASoC: fsl_micfil: Add i.MX943 platform support
On i.MX943, the FIFO data address is changed to 0x20~0x3c,
compared to previous version, there is a minus 4 offset,
so add a new regmap configuration for it.
And the bit width of CICOSR is changed to 5 bits, from bit
16th to 20th in REG_MICFIL_CTRL2 register, so update its

ASoC: fsl_micfil: Add sample rate constraint
On some platforms, for example i.MX93, there is only one
audio PLL source, so some sample rate can't be supported.
If the PLL source is used for 8kHz series rates, then 11kHz
series rates can't be supported.

So add constraints according to the frequency of available
clock sources, then alsa-lib will help to convert the
unsupported rate for the driver.

After commit 0edb555a65 ("platform: Make platform_driver::remove()

Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

ASoC: fsl_micfil: refactor deprecated strncpy
`strncpy` is deprecated for use on NUL-terminated destination strings [1].

A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on its destination buffer argument which is
_not_ always the case for `strncpy`!

In this case, though, there was great care taken to ensure that the
destination buffer would be NUL-terminated through the use of `len - 1`
ensuring that the previously zero-initialized buffer would not overwrite
the last NUL byte. This means that there's no bug here.

However, `strscpy` will add a mandatory NUL byte to the destination
buffer as promised by the following `strscpy` implementation [3]:
|       /* Hit buffer length without finding a NUL; force NUL-termination. */
|       if (res)
|               dest[res-1] = '\0';

This means we can lose the `- 1` which clears up whats happening here.
All the while, we get one step closer to eliminating the ambiguous
`strncpy` api in favor of its less ambiguous replacement like `strscpy`,
`strscpy_pad`, `strtomem` and `strtomem_pad` amongst others.

ASoC: fsl_micfil: rework quality setting
For the quality setting the quality setting register values are directly
exposed to the kcontrol and thus to userspace. This is unfortunate
because the register settings contains invalid bit combinations marked
as "N/A". For userspace it doesn't make much sense to be able to set
these just to see that the driver responds with "Please make sure you
select a valid quality." in the kernel log.

Work around this by adding get/set functions for the quality setting.

ASoC: fsl_micfil: simplify clock setting
The reference manual has this for calculating the micfil internal clock
divider:

         MICFIL Clock rate
clkdiv = -----------------
         8 * OSR * outrate

(with OSR == Oversampling Rate, outrate == output sample rate)

The driver first sets the MICFIL Clock rate to (outrate * 1024) and then
calculates back the clkdiv value from the above calculation.

Simplify this by using a fixed clkdiv value of 8 and set the MICFIL
Clock rate to (outrate * clkdiv * OSR * 8).

While at it drop disabling the clock before setting its rate. The MICFIL
module is disabled when the rate is changed and it is also resetted
before it is started again, so I doubt it's necessary to disable the
clock.

ASoC: fsl_micfil: Drop get_pdm_clk()
get_pdm_clk() calculates the PDM clock based on the quality setting,
but really the PDM clock is independent of the quality, it's always
rate * 4 * micfil->osr. Just drop the function and do the calculation
in the caller.

The OSR (OverSampling Rate) setting is set once to the default value
and never changed throughout the driver. Nevertheless the value is
read back from the register for further calculations. Just use the
default value because we know what we have written.

ASoC: fsl_micfil: drop error messages from failed register accesses
Failed register accesses are really not expected in memory mapped
registers. When it fails then the register access itself is likely not
the reason, so no need to have extra error messages for each regmap
access. Just drop the error messages. This also fixes some places where
a return value is concatenated using 'ret |=' and then returned as
error value.
