If the initialization is not finished, then filling input data to
the FIFO may fail. So it is better to add initialization finishing
check in the runtime resume for suspend & resume case.

And consider the case of three instances working in parallel,
increase the retry times to 50 for more initialization time.

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.

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.
