ASoC: SOF: control: Extend the optionality of IPC ops to IPC as well

The IPC ops are optional, but they require that the ops struct is to be
allocated with all callbacks set to NULL.

Update the code to extend the optionality to:
sdev->ipc == NULL
sdev->ipc->ops == NULL
sdev->ipc->ops->[tplg] == NULL
sdev->ipc->ops->[tplg]->control == NULL
sdev->ipc->ops->[tplg]->control->ops == NULL (treated optional currently)

ASoC: SOF: Handle control change notification from firmware

If the value/data associated with a control changes in SOF it will send a
notification (SOF_IPC_GLB_COMP_MSG with SOF_IPC_COMP_GET_VALUE/DATA).

We have support for binary volatile control type, but we might have
features where enum/switch/volume changes. Re-implementing everything as
volatile as well would be not much of a gain for several reasons:
- volatile controls would do an IPC all the time, regardless if there is a
need or not.
- We still don't have notification which forces userspace to continuously
poll.

When such notification arrives we use snd_ctl_notify_one() to signal
userspace about the change.

The kernel is prepared for two types of notification:
- the notification carries the new data for the control (num_elems != 0)
The new value/data is copied to the control's local data

- blank message about a change
The new flag for the scontrol (comp_data_dirty) is set and when next
time user space reads the value via the kcontrol's get callback we will
refresh the control's local data from the firmware.

ASoC: SOF: control: override volume info callback

ASoC dapm controls currently don't support more than 2 channels. This is
a problem for SOF-based devices where individual volume control cannot
be provided on the 4 DMIC input path.

If we want to provide controls for more than 2 channels, this patch
suggests a simple solution based on an override of the info callback.
For example, in the case with 4 channel DMIC PGAs, a sof_info callback
would be used. Mono and stereo cases will keep using the existing dapm
info callback.

A longer-term solution would be to remove the limits to 2 channels in
ASoC/DAPM/topology. This is a topic Intel is currently looking into,
e.g. by removing the use of 'reg' and 'rreg' fields and use arrays
instead. Such changes will be rather intrusive and touch multiple codec
and platform drivers. Removing restrictions is the right thing to do,
but this will need to be done in steps with lots of validation.

ASoC: SOF: acpi led support for switch controls

Currently sof doesn't support acpi leds with mute switches. So implement
acpi leds following quite shamelessly existing HDA implementation by
Takashi Iwai.

Mute leds can be enabled in topology by adding led and direction token
in switch control private data.

ASoC: SOF: dont wake dsp up in kcontrol IO

Always get kcontrol value from cache, set kcontrol value to DSP
when DSP is active. Kcontrol values will be restored when DSP boot up.
We will set the default value of kcontrol in sof_complete to make sure
the value is align with firmware.

ASoC: SOF: control: correct the copy size for bytes kcontrol put

The size for the bytes kcontrol should include the abi header, that is,
data->size + sizeof(*data), it is also aligned with get method after
this change.

ASoC: SOF: Add Sound Open Firmware KControl support

SOF exposes regular ALSA Kcontrols that are defined by topology. This
patch converts the Kcontrol IO to DSP IPC.

The current implementation is aligned with previous Intel solutions,
but is not optimal and can be improved:
a) for every get/put the host wakes up the DSP and generates an
IPC. The kernel should cache the values and generate an IPC only when
strictly necessary.
b) the firmware can be implemented to only instantiate the pipelines
and related control-related parts that are needed at a given time, and
power-gate the relevant SRAM blocks.

The development tasks for these two improvements has started, once
validated they will be provided in an update.
