There's a general move to use dev_pm_ops rather than bus specific functions
in order to facilitate work on the PM core. Do this conversion to WM2000.
The driver ought to be updated to work better in a multi-component model
but the mechanical conversion ensures that we avoid blocking PM core work
until that happens.

The utilities will be required by every machine driver. Including the
utility object directly into every machine driver causes a build failure
if the modules are actually built into the kernel, since each will define
the symbols exported by the utility file. Solve this by moving the
utility object into a separate module.

The default WM8958 jack detection handler implements a full set of buttons
and also support for video detection. Support for multi-button jacks is
fairly system specific and will usually require some tuning for headsets
so simplify the implementation to only report a simple short to ground
button, leaving multi-button headsets to be handled by system specific
code.

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.

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.
