Override NPU driver weak function prototypes to properly free
up resources after use.

The rpmsg struct used in response messages is not zero initialized so
later response messages may contain old data. To resolve this, the rpmsg
struct is now zero initialized for each new message.

There are instances of class members not being zero initialized in the
message handler. To avoid possible issues with using the class members
when they have an intermediate value, the constructors have been updated
to zero initialize all the member variables.

The semaphore created in the RProc constructor is never cleaned up. To
resolve this, the destructor will now delete the semaphore.

The constructor for the Rpmsg class does not zero-initialize its member
variables. This causes issues with the remoteproc library because it
thinks function pointers in the variables are set to valid functions
when they are actually just uninitialized values and using these
function pointer causes crashes and unexpected behavior.
To resolve this, the Rpmsg class constructor has been changed to
zero-initialize all its member variables.

The size of the memory used for the message handler's tensor arena will
always be rounded up to the next power of two when the Linux kernel
allocates it. Therefore, to align the tensor arena size with how the
memory is allocated and be able to use the full size allocated, the
tensor arena size must now be a power of two.

With the restructuring of the Linux kernel driver source files, some
macros and types in the rpmsg header was renamed to better namespace
their usage.
The message handler openamp application has been updated accordingly.

The source files for the Linux kernel driver has been restructured and
the common rpmsg header file has been renamed and moved to an include
folder.
The message handler openamp application has been updated accordingly to
use the new header file.

Currently if the inference to cancel is not found in the inference
queue, the message_handler_openamp will response with an error. The
inference may already be running and therefore not be in the queue
anymore or the inference is already done and the response is in the
mailbox queue.
In either case, responding with an error when the inference is not in
the queue isn't useful so the check has been removed. The Linux kernel
driver knows what inferences that are inflight and will track what
inferences that have been cancelled and handle it accordingly.

Designated initializer is not part of the C++ standard until C++20 and
requires a compiler extension to work in earlier versions. To ensure the
message_handler_openamp can be compiled with compilers without this
extension the usage has been removed.

Currently the message_handler_openamp overwrites the PMU values in the
response message each time operators are offloaded the NPU in an
inference request. To instead get the total PMU values for all the times
the NPU was used during the inference, the PMU values are now
accumulated instead.

Address translation for inference buffers and carveout areas have been
removed because the Linux Kernel NPU driver now provides device

To avoid having to use a hardcoded memory map to translate between the
Linux physical addresses and device addresses, a new entry type has been
added to the resource table where the host can provide the memory map to
use for the translation.

When the mailbox interrupt is triggered, the mailbox interrupt handler
will invoke the remote processor mailbox callback, which in turn will
use FreeRTOS's xSemaphoreGiveFromISR to wake up a task to handle the new
message.
Until now, the interrupt priority for the mailbox interrupt has been
left at its default value but this stopped working since FreeRTOS kernel
V10.6.0 because since that version, the ISR functions will only work
from an interrupt with the same or lower priority than
configMAX_SYSCALL_INTERRUPT_PRIORITY in the FreeRTOS configuration.
Therefore, a priority is now set for the mailbox interrupt that is
compatible with the FreeRTOS configuration used.

Patch adds an optional trace resource entry which can be enabled via
build flags. This patch also changes the resource table into a plain C
struct, which allows for link time assignment of trace resource address
and size.

The TFLM arena size was incorrectly surrounded by sizeof(), which
caused the arena size to be allocated to only 4 bytes.

The 'message handler' firmware was based on a custom interface between
Linux and the firmware. Because the kernel driver has been converted
into a rpmsg driver, the 'message handler' application has been updated
into an OpenAMP based firmware.
