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).

To reduce pop noise during playback stream start and stop the codec needs
to have the digital_mute callback implemented.
The codec need to be muted before the CPU dai has been stopped (McPDM).
Stopping the McPDM will generate a pop on the codec since no signal on the
PDM bus means full negative amplitude.
By managing the mute/unmute state of the outputs we can decrease the amount
of pop noise when playback starts or stops.

We need to free the irq at twl6040_remove() which is called when the machine
driver has been removed (the card has been removed).
If we fail to do that, next time when the machine driver is loaded the
codec's probe will fail since the irq has been already requested.
