This commit introduces the ingredients required for adding
fuzzing support in SOF. The main ingredients are as follows:
QEMU bridge: This creates the IO bridge to communicate with
the QEMU DSP
Core IA host support for BYT/CHT platforms: Provides the host
support for intializing the platform and communicating with
the QEMU DSP
Main application: The fuzzing application that sets up the
platform and initializes the communication with the QEMU DSP
Currently, running the fuzzer application only sets up the
platform IO bridge for communicating with the QEMU DSP,
boots the FW, parses the topology file and sets up the components
and connections in topology by sending the IPC messages to
the QEMU DSP. The next step is to add the fuzzing component
which will be responsible for sending fuzzed IPC messages
and monitoring the status.

The topology parser in testbench can be re-used for
the other applications like the fuzzer. In order to
accomplish this, this commit does the following:
1. Separate the topology parser into a separate project
(tplg_parser) which implements the callbacks for parsing
all the components in topology.
2. Add support for parsing new components such as host
pcm, dai and mixer
3. Include the topology parser as an external project
in the testbench.

Adds cache operations to alloc functions to get full
synchronized memory map between different cores.
Memory allocations aren't done so often so we can
afford to go through cache and perform so many
wtb/inv operations. This change allows slave cores
for allocation from runtime heap, buffer heaps etc.

Refactors timer a little bit, to make better usage
of timer id values. Right now every timer has also irq
field, which is used to identify which interrupt line
to enable/disable. We don't longer need timer id to represent
also timer irq, so let's set custom ids and simplify
things.

Instead of returning next period, schedule functions should return
state of the executed task. Period of the tasks is set during
initialization and doesn't change dynamically, so it doesn't make
sense to return it. With the new added SOF_TASK_STATE_RESCHEDULE
we can easily decide if the task is completed or maybe need to
be run once again.

Extracts flags to generic task data, so there is no need
for ll_schedule to keep them privately. Also changes the
way they are passed. From now on flags should be set only
during task initialization and not when starting scheduling.

Function responsible for putting FW notifications into the
queue is shared between all cores. In this function we should

We also need to move core check a little bit further,

Fixes very rare race condition, when multiple cores
schedule something in low latency scheduler. We should

On exceptions and panics, the code will reach panic_rewind. That
function will, among the other things it needs to do to dump the info,
will also dump the exception cause (exccause register). This means that
normally coredumps from panics and those from exceptions are
indistinguishable.
In this commit I reserve the maximum value for exccause (63) to signify
that the dump actually came from a panic instead of a hardware
exception. The easiest way I could see that would not duplicate code is
to simply set the exccause register to this reserved value (otherwise it
could be undefined, as it's not initialized at boot).
I also update the core dumper tool to use 63 as the value reserved for
panics instead of 0 (which is IllegalInstructionCause, a valid hardware
exception).

Before the commit the C exception handler table was declared empty
(suspiciously). This also caused my own tests to fail to call the panic
code whenever an exception occurred.
This commit fixes this by actually declaring the slots themselves and
initializing them to xtos_p_none, and also setting the correct size
(64 * 4 instead of 0).
