ASoC: mediatek: mt8188: Convert to RUNTIME_PM_OPS()
Use the newer RUNTIME_PM_OPS() macro instead of SET_RUNTIME_PM_OPS()
together with pm_ptr().

This optimizes slightly when CONFIG_PM is disabled, too.

ASoC: mediatek: mt8188: Add support for DMIC
Add support for the DMIC DAIs present on the MT8188 SoC. To achieve
that, add a DAI driver for DMIC and register it during probe, and
describe the AFE routes that connect the DMIC (I004-I011) to the UL9
frontend (O002-O009).

ASoC: mediatek: mt8188: Treat DMIC_GAINx_CUR as non-volatile
The DMIC_GAINx_CUR registers contain the current (as in present) gain of
each DMIC. During capture, this gain will ramp up until a target value
is reached, and therefore the register is volatile since it is updated
automatically by hardware.

However, after capture the register's value returns to the value that
was written to it. So reading these registers returns the current gain,
and writing configures the initial gain for every capture.

>From an audio configuration perspective, reading the instantaneous gain
is not really useful. Instead, reading back the initial gain that was
configured is the desired behavior. For that reason, consider the
DMIC_GAINx_CUR registers as non-volatile, so the regmap's cache can be
used to retrieve the values, rather than requiring pm runtime resuming
the device.

ASoC: mediatek: mt8188: Mark AFE_DAC_CON0 register as volatile
Add AFE Control Register 0 to the volatile_register.
AFE_DAC_CON0 can be modified by both the SOF and ALSA drivers.
If this register is read and written in cache mode, the cached value
might not reflect the actual value when the register is modified by
another driver. It can cause playback or capture failures. Therefore,
it is necessary to add AFE_DAC_CON0 to the list of volatile registers.

ASoC: mediatek: Use common mtk_afe_pcm_platform with common probe cb
Since the mtk-afe-platform-driver generic mtk_afe_pcm_platform now has
a common .probe() callback, there is no reason to keep duplicating this
function over and over in the SoC specific AFE-PCM drivers: switch over
to register with the common bits instead.

Note that MT8186 was left out of this because it is registering some
extra sinegen controls in the AFE-PCM probe callback and needs extra
cleanups to be able to use the common bits.

ASoC: mediatek: mt8188: fix use-after-free in driver remove path
During mt8188_afe_init_clock(), mt8188_audsys_clk_register() was called
followed by several other devm functions. The caller of
mt8188_afe_init_clock() utilized devm_add_action_or_reset() to call
mt8188_afe_deinit_clock(). However, the order was incorrect, causing a
use-after-free issue during remove time.

At probe time, the order of calls was:
1. mt8188_audsys_clk_register
2. afe_priv->clk = devm_kcalloc
3. afe_priv->clk[i] = devm_clk_get

At remove time, the order of calls was:
1. mt8188_audsys_clk_unregister
3. free afe_priv->clk[i]
2. free afe_priv->clk

To resolve the problem, it's necessary to move devm_add_action_or_reset()
to the appropriate position so that the remove order can be 3->2->1.

ASoC: mediatek: mt8188-afe-pcm: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
