The DAI and host components states must be preserved during pause so that
when normal pipeline positions are used on resume. i.e. pause just looks
like a very long pipeline schedule.

The circular trace buffer can overflow if too much trace data is sent
before it can schedule a DMA copy to flush the data. This overflow
causes the avail bytes counter to be greater than the buffer size and
means the DMA copy is rescheduled until avail is 0 (repeating old data).
Fix this by resetting avail to 0 when we overflow.

Add a simple system monitoring agent that can detect when FW does not
execute correctly. The assumption is that FW will always idle from time
to time and this idling can be monitored by the SA. The FW wont idle if
it's thrashing, continually interrupted, continually running work or
continually rescheduling a task.
The SA will emit trace and panic if idle is not entered for a specific time
period.

This patch changes the condition for limiting the smallest gain to
eliminate a never executed code part when VOL_MIN is defined as zero. The
variable v is unsigned integer so less than zero is not possible.
The functionality is not modified by this patch.

Add a debug option that can detect deadlock and panic(). The deadlock
detection attempts to acquire a lock several times before giving up
and causing a panic() taht dumps the deadlock details.

Add message count and overflow detection to the trace position output
so that kernel and userspace can detect the trace buffer has overflowed.

Currently the trace initialisation must be performed after DMAC init
has completed. This means we miss the trace output from any platform
device initialisation.
Split the DMA trace initialisation into two parts so the trace buffer
is allocated early on and can accept messages meaning we dont miss any
device initialisation trace.

For memory to memory copy(burst_elems initialized to be 0),
we set msize to default value 3, that is 2 ^ 3 = 8 items for
each burst transaction.
For DMA copying which related to peripheral device(source or
destination), we will use the configured burst_elems, which
usually means the number of data items, e.g. slot number for
SSP dai fifos.

We should set burst_elems for dma peripheral dev copy, for
dai/ssp, it should be set to valid slot number, otherwise,
the dma may copy in wrong burst size and data will run with
wrong speed.

We have 5 critical arguments in the test generator but only used 3 for
the naming, this will make some files be overwritten.
Refine the name method to let these 5 arguments show in the tplg name.
Also we decide the pipe type in one of the argument, test-ssp.m4 and
test-src-ssp.m4 are almost the same, just remove one.

The volume component can change the sink data format depending on sink
component/pipeline topology configuration. This change is set locally,
but not to the host params that are passed downstream.
Fix this so that downstream components can check params match their
topology configuration.
Tested with test-passthrough-48k-vol-ssp2 and reef-byt-rt5651
topology files. Note that there are quite a few underflows likely added by
recent changes, more work needed to identify what goes on.

case by Pierre)
