As there is max one device per driver handle, store the device
struct in the driver struct and get rid of the malloc call from
the device init code.

Add new weak function ethosu_address_remap() that allows the addresses
for QBASE and BASEP to be remapped.

Base address 1 points at the TFLM arena and is by default routed
over AXI 0. For the spilling use case with both model and arena in
DRAM it would make more sense to route base addresses 0 and 1
over AXI 1.
For Ethos-U65 the default settings should correspond to the spilling
use case.
The AXI limits should have different max values depending on the NPU
architecture.

Add reference counted ethosu_request_power(),
ethosu_release_power() functions. While there are
active requests, disable the Q-channel power gating
of the Ethos-U device, leaving the device powered on.
Note that clock gating is implemented to follow the
state of the power gating.
Add ethosu_soft_reset() function. Restore power-
and clock gating state after reset.
Refactor and simplify driver code to use the new
functions.

Add an asynchronous API to the driver. The current synchronous API
is now using the new async API internally. The main new functions
are ethosu_invoke_async() and ethosu_wait(). Every successfull call
to ethosu_invoke_async() must be followed by a call to ethosu_wait()
to get the status of the inference. The wait function can be called
in a blocking or non-blocking mode by specifying the `block`
argument to true/false. The regular synchronous invoke function is
implemented as a invoke_async followed by a wait(block=true) call.
Short sommary of changes:
- Add an internal ethosu_job struct to keep track of
inference data and job state.
- Use async API in blocking mode for normal flow
- Change default semaphore implementation to binary type
- Move error prints out of interrupt context
- Move ethosu_inference_begin() callback to right before HW invoke
- Always call ethosu_inference_end() callback, even in case of errors
- On NPU error, do not keep NPU powered after being reset

A continuation of the spring clean/refactor work. Create a
better separation between driver and device(s).
A short summary of what this commit contains:
- Split device and driver
- Simplify and hide the internal device interface
- Remove (broken) abort inference functionality
- Refactoring of structure
- Optimizations and bugfixes
