As a first step to have a clearer separation of the different parts of
the kernel driver, the source files have been placed into separate
directories according to their purpose and the different parts are only
allowed to use headers from another part in the include folder.
Files have been renamed accordingly to namespace them by their purpose.

To allow the NPU kernel driver to allocate and use DMA memory internally
without creating a buffer instance, the DMA memory management has been
split out from the buffer code.

To ensure that no compilation warnings goes unnoticed, the kernel
modules are now built with the -Werror flag so all warnings are treated
as errors.

To ensure that the Linux kernel NPU driver and the firmware used are
compatible, the NPU driver will now request and verify the protocol
version when setting up the device during the probing.

Avoid to use pointers to kernel memory as identify messages, prior this
change, if memory is reused that can lead to unexpected conflicts.
Remove ref counting from capabilities and network_info since memory is
freed in only one place.
Finally, extract the capabilities code in its own files.

Send cancel inference messages to the ethosu subsystem to abort
inference execution there. Also mark inference as aborted in the
linux driver stack itself, so pending inference messages are not
resent when resetting the firmware.

Implement kernel watchdog that detects when firmware becomes
unresponsive.

Add UAPI and core message that allows user space space to fetch
information about network models built into the firmware.
