That bug slipped in during a rebase session of the driver refactoring.

commit b047e1cc (ASoC: ac97: Support multi-platform AC'97) introduced
some build failures for modules wanting to access the generic
soc_ac97_ops.  For example:

ERROR: "soc_ac97_ops" [sound/soc/codecs/snd-soc-wm9712.ko] undefined!

To fix, export soc_ac97_ops to modules.

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).
