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.

The PMU event counter value is an accumulation of 32-bit values during
the inference and to ensure the total value fits in the rpmsg message
and UAPI, the variable holding the value has been changed to 64-bit.
The driver library, Python wrapper and inference runner have been
changed accordingly to support the 64-bit values.

To not allow the buffer for a network instance to be changed after
creation, the create network UAPI will now take the network model data
as a user buffer. The content of the user buffer is copied into an
internally allocated DMA buffer that cannot be accessed by the user.
This breaks the current API so the Linux kernel NPU driver version and
the driver library version have been given major version bumps. All the
tests, documentation and other applications affected by the changes have
been updated accordingly.

The UAPI no longer supports the buffer capacity, offset and resize
functionality. Instead, the UAPI now only accepts a fixed size given at
the creation of the buffer. This change was made because the features
were not used and made the buffer handling more complicated. The user
knows how big buffers they need for their networks so they don't need
resize support or partial buffer usage support by having separate size
and capacity with an offset.
Without these features, the buffer instance no longer needs any IOCTL
call support so it has been removed. However, to still be able to check
the size of a buffer from its file descriptor, seek support has been
implemented so lseek and similar functions can be used to get the size.
The driver library's clear function that previously only reset the size
and offset values of the buffer will now clear the buffer content
instead.
These are breaking changes so the Linux kernel NPU driver version and
the driver library version have been given major version bumps. All the
tests and other applications affected by these changes have been updated
accordingly.

In order to avoid struct layout misalignment issues between user and
kernel space, raising from size of enum members being implementation-
defined, the enum members of structs in the UAPI header file have now
been replaced with fixed-width integers.

The kernel driver's version is now exposed in the UAPI so the UAPI user
can validate that they are compatible with the kernel driver in use.

The current implementation of the protocol version request IOCTL call
doesn't return any version information and the protocol version is not
needed by any userspace program as it's for the communication between
the Linux kernel NPU driver and firmware. The IOCTL call has therefore
been removed from the UAPI and the inference runner has been updated
accordingly.

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.

Introduce a 32b magic for each message. Verify the magic for
all incoming messages.
Add reset function - in case of protocol error, effectively
reset/empty the incoming queue.
Add an error message type and message
Add version request/response
Verify payload length of responses (when applicable)
