sof_get_control_data returns negative values even though the return
value is defined unsigned (size_t). So change the return value type to
int and add the data size as pointer argument to sof_get_control_data to
avoid ambiquity in the meaning of the return type.

The Audio Link Hub DAI does not require any static configuration from
topology for now. We still need to pass the frame rate and format to
firmware.

Currently when loading sof process components there's a check if binary
control data is associated with it. If found the data is extracted to be
part of component loading and initialization. If binary data exceeds the
ipc max size, loading fails with error as large message support is only
implemented in set_get_data method. So make the process loading use
set_get_data to enable large parameters in component initialization.
Also refactor the process component loading function as it digs out 3
times almost identical information of related controls. This is
redundant, looks ugly and makes it difficult to understand the
mechanism. So make a function out of fetching the control data and use
it in process loading.

Some codecs require BCLK to be on for some time, before sending
any data. SOF can enable BCLK and then wait for guaranteed time,
before starting DMA on SSP start.

The recommended HDA HW programming sequence for setting
the DMA format requires that the link DMA and host DMA
channels be coupled before setting the format. This
change means that host DMA or link DMA channels be
reserved even if only one is used.
Statically assigned link DMA channels would mean that
all the corresponding host DMA channels will need to be
reserved, leaving only a few channels available at run-time.
So, the suggestion here is to switch to dynamically assigning
both host DMA channels and link DMA channels are run-time.
The host DMA channel is assigned when the pcm
is opened as before. While choosing the link DMA channel,
if the host DMA channel corresponding to the link DMA channel
is already taken, the proposed method checks to make
sure that the BE is connected to the FE that has been assigned
this host DMA channel. Once the link DMA channel is assigned,
an IPC is sent to the DSP to set the link DMA channel.
The link DMA channel is freed during hw_free() and also in the
SUSPEND trigger callback. It will be re-assigned when hw_params
are set upon resume.

The settling time of DMIC DC level is both platform and used
microphone model specific. The unmute gain ramp is used to conceal
most of the large DC level seen in beginning of capture. This patch
adds into the DMIC DAI IPC struct a new field called unmute_ramp_time
and a new token SOF_TKN_INTEL_DMIC_UNMUTE_RAMP_TIME. The value is the
ramp length in milliseconds (ms).
The ABI minor version is incremented for this backwards compatible
change.

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace the following form:
sizeof(struct sof_ipc_ctrl_data) + sizeof(struct sof_ipc_ctrl_value_chan) *
le32_to_cpu(mc->num_channels)
with:
struct_size(scontrol->control_data, chanv, le32_to_cpu(mc->num_channels))
and so on...
This code was detected with the help of Coccinelle.

Currently there are two null checks of pointer dai in function
sof_connect_dai_widget and yet there is no null check of dai
at the end of the function when checking !dai->name. The latter
would be a null pointer deference if dai is null (as picked up
by static analysis), however the function is only ever called
when dai is successfully allocated, so the null checks are
redundant. Clean up the code by removing the null checks.
