snd_soc_dapm_new_widgets() works on the ASoC card as a whole not on a specific
DAPM context. The DAPM context that is passed as the parameter is only used to
look up the pointer to the card. This patch updates the signature of
snd_soc_dapm_new_widgets() to take the card directly.

Call snd_soc_dapm_new_widgets() before the auto non-connected pins have been
marked as not connected will power the system under the assumption that those
pins are connected. Once the pins have been marked as disconnected the system
there will be an additional power run. This can cause unnecessary power
transitions. Calling snd_soc_dapm_new_widgets() only after the pins have been
marked as non-connected avoids this.

Each time snd_soc_dapm_new_widgets() is called it will instantiate all the
widgets and routes that have been added so far and then power them. Doing this
multiple times before the card is fully initialized and all widgets have been
added can cause unnecessary and even invalid power state transitions which can
result in extra register writes and and also might cause clicks and pops.

Some more fixes and enhancements, and also a bunch of refectoring for
AC'97 support which enables more than one AC'97 controller driver to be
built in.
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.

Help avoid noise from the power up of the capture path propagating through
into the start of the recording (especially noise caused by the ramp of
microphone biases) by keeping the capture muted until after we've finished
powering things up with DAPM in the same manner we do for playback. This
allows us to take advantage of soft mute support in the hardware more
effectively and is more consistent.
The core code using the existing digital mute operation is updated to take
advantage of this. Some additional cases in the soc-pcm code and suspend
will need separate handling but these are less practically relevant than
the main runtime stream start/stop case.
Rather than refactor the digital mute function in every single driver a
new operation is added for drivers taking advantage of this functionality,
the old operation should be phased out over time.
