wire-ORs multiple interrupt sources, such as stream, IPC, SoundWire and
wakes. This patch adds the ability to trace each event occurrence.

Merge series from Nícolas F. R. A. Prado <nfraprado@collabora.com>:
The i2s ports on MediaTek SoCs only support a single data lane. In order
to achieve full-duplex operation thus two i2s ports, one for input and
one for output, need to be used together and sharing a single clock from
one of the ports.
This clock sharing setting was previously read by the sound platform
driver from the devicetree, but given that the input/output pairing is
closely related to which codecs are connected to which ports, the
machine sound driver can infer and set it, so that no DT property is
required.
At this point only mt8183-kukui was using the DT property, but given
that this property was never documented, and that the API introduced in
this series makes it obsolete, the undocumented DT property can safely
be removed.
This series adds a function to allow setting the i2s shared clocks,
makes use of it in the machine drivers as required, and removes the no
longer required DT properties and support for them in the drivers, for
all of mt8192, mt8183 and mt8186.

One of the debugging/logging features for an IPC4 based firmware is the use
of the debug window to deliver log messages to host via the shared SRAM.
The initial implementation of the mtrace supports only TGL/MTL style of
logging, but can be extended to support other types, like APL, SKL, CNL,
etc.
The window is split into 16 'slots' where the first slot contains the
descriptors for the remaining 15 slots.
Each DSP core logs to a separate slot and the slot allocation is not fixed,
we can not assume that the first slot is always used by core0 for example.
The firmware sends LOG_BUFFER_STATUS message when new log batch is
available from one of the cores (after it updated the write_ptr in the
given slot).
Host should update the read_ptr in the same slot when it has taken out log
data.
The patch also updates the sof_ipc4_fw_data struct with parameters needed
for the mtrace to be enabled and used safely.

Failing to do so will produce errors when applying the SOF topology
leading to card registration failure (so, no sound).
While at it, also make sure to fill the topology_shortname as required.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
Continuation of recent upstream discussion [1] regarding user string
tokenization.
First, parse_int_array_user() is introduced to allow for splitting
specified user string into a sequence of integers. Makes use of
get_options() internally so the parsing logic is not duplicated.
With that done, redundant parts of the sound driver are removed.
Originally similar functionality was added for the SOF sound driver. As
more users are on the horizon, it is desirable to update existing
string_helpers code and provide a unified solution.
