ASoC: mediatek: mt6358: fix UNINIT problem
Coverity shows decaring variable reg without initializer. When
regmap_read returns an error, reg keeps the value left from earlier
computation. To prevent from the unexpected result in the case, assign
0 to reg.

ASoC: mt6358: Remove undefined HPx Mux enumeration values
The HPx Mux enumerations define values 5, 6 and 7 but describe them as
"undefined" and map them to the value 0 on writing. Given the descriptions
and behaviour it seems that these values are invalid and should not be
present in the register, the current behaviour is detected as problematic
by mixer-test:

# # HPL Mux.0 expected 5 but read 0, is_volatile 0
# # HPL Mux.0 expected 6 but read 0, is_volatile 0
# # HPL Mux.0 expected 7 but read 0, is_volatile 0

Remove the values from the enumeration, this will prevent userspace setting
them.

ASoC: mt6358: Validate Wake on Voice 2 writes
Currently the Wake on Voice 2 control accepts and stores any value written
but it reports that only 0 and 1 are valid values. Reject any out of range
values written by userspace.

ASoC: mt6358: Fix event generation for wake on voice stage 2 switch
ALSA control put() operations should return 0 if the value changed so that
events can be generated appropriately for userspace but the custom control
for wake on voice stage 2 doesn't do this, fix it.

ASoC: mediatek: mt6366: support for mt6366 codec
Mt6366 is a new version of mt6358, and they are same about audio part.
So we can reuse the driver of mt6358 that add a new compatible string
inside of the mt6358 driver.

ASoC: mt6358: Add endianness flag in snd_soc_component_driver
The endianness flag is used on the CODEC side to specify an
ambivalence to endian, typically because it is lost over the hardware
link. This device receives audio over an I2S DAI and as such should
have endianness applied.

As the core will now expand the formats to cover both endian types,
remove the redundant manual specification of both.

ASoC: mediatek: mt6358: add delay after dmic clock on
Most dmics produce a high level when they receive clock. The difference
between power-on and memory record time is about 10ms, but the dmic
needs 50ms to output normal data.

This commit add 100ms delay after SoC output clock so that we can cut
off the pop noise at the beginning.

ASoC: mediatek: mt6358: save output volume for mixer controls
Output volume settings from mixer controls would be lost.

Imagine that "Headphone Volume" has set to -10dB via amixer:
- in mtk_hp_enable()
  - hp_store_gain() saves the volume setting -10dB from regmap_read()
    to ana_gain[AUDIO_ANALOG_VOLUME_HPOUTL]
  - headset_volume_ramp() ramps up from -10dB to -10dB
- in mtk_hp_disable()
  - headset_volume_ramp() ramps down from -10dB to -40dB

Next time in mtk_hp_enable(), hp_store_gain() would save -40dB but
not -10dB.  As a result, headset_volume_ramp() would ramp from -10dB to
-40dB (which is mute).

ASoC: mediatek: mt6358: initialize setting when ramping volume
Mt6358 ramps up from the smallest volume (i.e. -10dB) to target dB when
opening and ramps down from target dB to mute (i.e. -40dB) when closing.
If target is equal to -10dB when opening, headset_volume_ramp() simply
leaves current setting (which may not be -10dB) unchanged.

Execute the loop at least once to initialize the setting to the
starting point (i.e. from).
