If an inference fails to be cancelled and it is still in a pending
state, reset the whole firmware. Indeed the assumption is that
something is at fault on the firmware side and it is not progressing.

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.

The .da_to_va has different signatures for different kernel versions.
Add kernel version checks to pick the correct one.

There is not real need for the linux_driver_stack to know about tflite
and flatbuffers. A better approach is to just pass the buffer to the
firmware to be processes, i.e., either parsed or executed.
This solves issues when linux_driver_stack and firmware are not in
sync with the same library versions.

Reset the firmware if it becomes unresponsive. Use ping to send
keep alive requests.
Only monitor ping and inference request messages. The other messages
pass no resources to the firmware and can be cancelled without
resetting the firmware.

When bailing out on errors in the constructors of Buffers or Networks,
the open file descriptor should be closed since the descructor will
never be called.

As of kernel version v5.12 the amba_driver.remove is expected to be of
'static void' rather than the previous 'static int'. This patch updates
the mhu files to comply with kernel version v5.12.
