ASoC: don't register AC97 devices twice

With generic AC97 ASoC glue driver (codec/ac97.c), we get following warning when
the device is registered (slightly stripped the backtrace):

kobject (c5a863e8): tried to init an initialized object, something is seriously
                    wrong.
[<c00254fc>] (unwind_backtrace+0x0/0xec)

[<c0062ddc>] (sys_init_module+0x12b0/0x1454)

This happens because the generic AC97 glue driver creates its codec->ac97 via
calling snd_ac97_mixer(). snd_ac97_mixer() provides own version of
snd_device.register which handles the device registration when
snd_card_register() is called.

To avoid registering the AC97 device twice, we add a new flag to the
snd_soc_codec: ac97_created which tells whether the AC97 device was created by
SoC subsystem.

ASoC: Fix incorrect parameter to snd_soc_codec_volatile_register

We need to pass the register index and not the register value.
This patch depends on my previous patch "ASoC: Delegate to hw
specific read for volatile registers".

The code can't really cope with I/O errors, so it would be better
to be consistent throughout all cache functions and return -1 instead

There is no need to reset the codec and perform cache sync if none of the

required.

ASoC: tlv320aic3x: Add runtime regulator control to aic3x_set_bias_level

Now all the regulators are disabled when entering into SND_SOC_BIAS_OFF
and enabled when coming back to SND_SOC_BIAS_STANDBY state. Currently this
runtime control happens only with suspend/resume as this patch does not
change the default idle behavior.

This patch manages all the regulators and reset since it seems that register
sync is needed even if only analog supplies AVDD and DRVDD are disabled.
This was noted when the system was running with idle behavior changed and
IOVDD and DVDD were on.

It is not known are all the registers needed to sync or only some subset of
them. Therefore patch plays safe and does always full shutdown/power-up.

ASoC: tlv320aic3x: Add virtual output pin Detection

Purpose of this virtual Detection pin is to keep codec bias on whenever the
GPIO or jack detection features are needed.

Jack detection needs a mic bias so machine drivers can construct a following
route for instance for keeping the path and codec bias on:

"Input Jack" -> "Mic Bias xV" -> "Detection" -> detection block inside codec.

For the GPIO the machine driver can force the pin on with
snd_soc_dapm_force_enable_pin.
