It turns out that the TAS5086 doesn't like channel start parts to be
empty, and if all channels are configured to Mid-Z, part 1 has to be
used.

Currently we can only have a single platform built in with AC'97 support
due to the use of a global variable to provide the bus operations. Fix
this by making that variable a pointer and having the bus drivers set the
operations prior to registering.

This is not a particularly good or nice approach but it avoids blocking
multiplatform and a real fix involves fixing the fairly deep problems
with AC'97 support - we should be converting it to a real bus.

The ADAU1701 has 2 hardware pins to configure the PLL mode in accordance
to the MCLK-to-LRCLK ratio. These pins have to be stable before the chip
is released from reset, and a full reset cycle, including a new firmware
download is needed whenever they change.

This patch adds GPIO properties to the DT bindings of the Codec, and
implements makes the set_sysclk memorize the configured sysclk.

Because the run-time parameters are unknown at probe time, the first
firmware download is postponed to the first hw_params call, when the
driver can determine the mclk/lrclk divider. Subsequent downloads
are only issued when the divider configuration changes.

The TAS5086 has two alternative modes to start its PWM channels, Mid-Z
and Low-Z. Which one to use depends on how the PWM power stages are
connected to the TAS5086.

This patch adds 6 optional boolean properties to the DT bindings of the
driver which allow the user to configure each individual channel to the
Mid-Z scheme, and leaves all the others to the default (Low-Z).

Some runtime-determined constraints might need to be satisfied prior to
firmware loading, so the actual download and releasing the device from
reset has to be postponed. Factor it out first, so we have everything at
one place.

This also changes the behaviour in a way that adau1701_i2c_probe() will
assert the reset line, and wait for the codec probe to release it.

When calling snd_soc_dapm_sync(), it eventually tries to lock the same mutex
already locked in snd_soc_dapm_put_volsw_aic3x() and a deadlock occurs. By
moving the mutex unlock to just before snd_soc_dapm_sync(), this deadlock is
prevented. This problem was introduced in Linux 3.5

Rename `dirty' to `set' as it is a bit more descriptive.  A set
control is any control that has been set by the user.  We need to ensure
that everytime we boot the DSP we sync out any controls that were
set.

We could at some point start keeping track of the default values of
the controls to suppress some of the device I/O.
