Now codec hits the SND_SOC_BIAS_OFF also when it is idle. This is also
the default state after probing and codec is left unconfigured and
unpowered by default. Initialization will happen when the bias state changes
and aic3x_set_power does power-up and cache sync.

There is no need to reset the codec and perform cache sync if none of the
supply regulators were not disabled. Patch registers a notifier callback for
each supply and callback then sets a flag to indicate when cache sync is
required.

HW writes are also needless when codec bias is off so cache_only flag is set
independently of actual supply regulators state.

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.

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.

Complete the phasing out of aic3x_read_reg_cache, aic3x_write_reg_cache,

This patch uses in aic3x_read the codec->hw_read that points to a function
implemented by soc-cache. Only use for aic3x_read is if wanting to read
volatile bits from those registers that has both read-only and read/write
