This patch adds SND_SOC_DAPM_PGA_E to the headset path, which handles
the headset ramp up and down sequences needed for the pop noise
removal.

With this patch the order of the internal components in the twl4030
codec is turned on and off in a correct order.

Restructuring the twl4030 codec's DAPM routing to be able to handle the power
sequences correctly.

The twl4030 codec internal implementation have this order:
DAC -> Analog PGA -> Mixer/Mux

While the ASoC framework expects the following order:
DAC -> Mixer -> Analog PGA

This patch moves the Analog PGA handling from SND_SOC_DAPM_PGA to _MIXER and
adds two levels of mixer to handle the digital and analog loopback
functionality.

Now the analog loopback does not powers on any of the DACs.

Add a control for selecting the codec operation mode. TWL4030 codec
has two modes:
- Option 1. Audio only (4 audio DACs)
- Option 2. Voice/Audio (2 audio DACs and voice ADC/DAC)

Control is restricted when a stream is ongoing, since codec's
operation mode cannot be changed on-the-fly.

The WM9712 can be configured by resistor strapping GPIO4 to behave like
the WM9713 and default to leaving the AC97 link disabled after cold
reset until a warm reset occurs.  In this configuration we need to issue
a warm reset after cold to bring the link up so do so.  The warm reset
will be harmless on systems that don't need it.

codecs. It is implemented using the new SOC_DOUBLE_EXT macro to catch
the put function and store the information about manually set mute
controls from userspace. When a manual mute is set, we don't want the
soc core to un-mute the outputs.
