ASoC: Run bias level changes for all DAPM contexts in parallel

As bias level changes can be quite time consuming and the bias changes
for multiple devices aren't strongly tied to each other (if anything it
can be advantageous to bring different devices up together) we can improve
the state transition time for multi-component systems by running the bias
level changes for all the devices in parallel. This is very simple to
achieve using the kernel async functionality so use that to schedule the
work.

This should have no practical effect for the overwhelming majority of
systems which have a single DAPM context - we'll bounce into another
thread to do the bias level change but otherwise everything will happen
in exactly the same order as it did before.

ASoC: Tegra: Harmony: Explicitly set mic enables

Harmony has both an external mic (a regular mic jack) and an internal mic
(a 0.1" two-pin header on the board).

The external mic is connected to the WM8903's IN1L pin, and is supported
by the current driver.

The internal mic is connected to the WM8903's IN1R pin, and is not supported
by the current driver.

It appears that no Harmony systems were shipped with any internal mic
connected; users were expected to provide their own. This makes the
internal mic connection less interesting.

The WM8903's Mic Bias signal is used for both of these mics. For each mic,
a GPIO drives a transistor which gates whether the mic bias signal is
actively connected to that mic, or isolated from it.

The dual use of the mic bias for both mics makes a general-purpose complete
implementation of mic detection using the mic bias complex. So, for
simplicity, the internal mic is currently ignored by the driver.

This patch configures the relevant GPIOs to enable the mic bias connection
to the external mic, and disable the mic bias connection to the internal
mic. Note that in practice, this is the default state if these GPIOs aren't
configured.

ASoC: CX20442: fix wrong reg_cache_default content

Content of the CX20442's snd_soc_codec_driver.reg_cache_default pointed
area, introduced with my recent NULL pointer dereferece fix (commit
f019ee5feb344ff0b22b58df4568676295aae14f), occured wrong after further
testing, more thorough than just booting successfully. There are two
problems with it:

1) It should read
(1 << CX20442_TELOUT) | (1 << CX20442_MIC),
   not
CX20442_TELOUT | CX20442_MIC.

2) While correctly matching actual codec hardware state on boot when
   fixed per 1), a few more code modifications would still be required
   to reflect that state not only into register cache, but also force
   them into DAPM pins state, otherwise an inconsitency occures which
   may prevent further codec state changes from being applied correctly.
   As a result, the phone stops ringing after reboot, until someone
   picks up the handset for the first time.

Revert that reg_cache_default content to a working, previous de facto

ASoC: codecs: wm8753: Fix DAI mode switching

The wm8753 codec supports switching between different DAI modes.
The current drivers tries to implement this by changing the DAI driver at
runtime. But to properly work this would require support from the ASoC core.

So this patch takes a different approch on how the DAI mode switching is
implemented.

The only difference, from a driver point of view, between the different DAI modes
is how to program the DAI format to the hardware. So what this patch is, it
stores the current format for each DAI in the drivers private struct and when
the DAI mode is changed the format gets simply reprogrammed according to the
new DAI mode.
