ASoC: nau8824: use 64-bit arithmetic instead of 32-bit
Add suffix ULL to constant 256 in order to give the compiler complete
information about the proper arithmetic to use.

Notice that such constant is used in a context that expects an
expression of type u64 (64 bits, unsigned) and the following
expression is currently being evaluated using 32-bit arithmetic:

256 * fs * 2 * mclk_src_scaling[i].param

ASoC: nau8824: user configuration of key detection
The SAR ADC of key press detection varies depending on headset.
We can't make a set of common threshold values for every case.
Therefore, the driver provides configuration for user and
they can set up values by UCM configuration.

ASoC: nau8824: recover system clock when device changes
User reports an issue in Ubuntu about the device switch upon playback.
We find the FLL will disalbe when switching headphone to speaker.
The pulseaudio will stop the headphone and close its power. Then,
it just opens the speaker and turn on its power. Therefore,
the supply of system clock does the OFF event and disables FLL.
But the FLL doesn't enable again when the speaker powers on.

The patch adds the recovery of system clock to enable FLL again
for this case. And it covers the case that system clock from MCLK.

ASoC: nau8824: replace codec to component
Now we can replace Codec to Component. Let's do it.

Note:
	xxx_codec_xxx()		->	xxx_component_xxx()
	.idle_bias_off = 0	->	.idle_bias_on = 1
	.ignore_pmdown_time = 0	->	.use_pmdown_time = 1
	-			->	.endianness = 1
	-			->	.non_legacy_dai_naming = 1

ASoC: nau8824: change FVCO maximum threshold
Change the maximum of FDCO which remains between 90MHz-100MHz.
FDCO must be within the 90MHz-100MHz or the FFL cannot be
guaranteed across the full range of operation.

ASoC: nau8824: condition for clock disable
There are headphone and speaker outputs in NAU88L24. During the
playback, the codec should not change the clock status when
switching these outputs.

ASoC: nau8824: move key irq after jd done
It is possible to get the fake key press interruption when the codec
do jack detection. We think it's proper to move the key interruption
configuration after jack detection done.

a180ba45b1 ASoC: codecs: add const to snd_soc_codec_driver structures
Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.
Done using Coccinelle:
