NPU driver interface currently have functions which have been stepped
each time a compatibilty breaking changed has been introduced. Old
entrypoints have been redefined with macro to use the latest version
for backwards compatibility. This series of patches will remove any
such functions and macro to unify the interface.
Update: Remove all "_v"-functions and make the latest version the base
entrypoint
Update: Remove all redefine macros to only allow base entrypoint
Note: static inline ethosu_invoke_v2() is kept as it is needed for
tensorflow backwards compatibility. Will be removed in later patches.

Changed so that power_request bit will be set if ETHOSU_POWER_Q_DISABLE
instead of ETHOSU_CLOCK_Q_DISABLE.

Currently clock request is enabled, which means NPU will
only request clock when working. When NPU is going into idle it will no
longer request clock and thus PMU won't be clocked either, and thus
affect the cycle counter.
Added: enum for request clients (PMU or INFERENCE).
Added: clock_request added to driver struct (bit 0: PMU, bit 1:
INFERENCE) which keeps track of which client requests clock.
Added: power_request added to driver struct (bit 0: PMU, bit 1:
INFERENCE) which keeps track of which client requests power.
Added set_clock_and_power_request(...) updates clock_request and
power_request depending on which client calls it. Sets clock and power
if both PMU and INFERENCE requests it.
Added: Call set_clock_and_power_request(...) from PMU.
Changed: replace ethosu_set_clock_and_power(...) with
set_clock_and_power_request(...) in ethosu_init and ethosu_invoke

Allow the IRQ handler to be overridden for test cases that operate
directly on top of the device driver.

Added: Weak linked symbols for locking if RTOS overrides
Added: Semaphore Producer (release a reserved driver)
Added: Semaphore Consumer (all drivers reserved and waiting for returned driver)
Added: Mutex protect thread sensitive driver access
Added: Weak linked symbols for yielding & resuming thread/task while waiting for IRQ
Added: static inline function of ethosu_invoke_v2(...) for backwards compatibility

If NPU power is guaranteed always on parts of driver setup can be omitted to reduce the number of cycles required to setup the NPU drivers.
By enabling dev_power_always_on, the setup cycles are reduced by approx. ~50%. (4462->2238 in prologue, 1167->642 in epilogue)

Using a cpu without proper interrupt handling is not really usefull in
this context, so remove that option.

The addition of init_v3 accidentely changed default values for soft
resetting Ethos-U. Restore the default parameters to non-secure, user
mode for init_v1 and init_v2 and also make sure to check return value
from ethosu_soft_reset.

Implement a weak linked function to handle the data cache.
If the specific device is implementing a data cache the function should
be overriden with device specific implementation of the flush/invalidate
functions to make sure that the cache is properly maintained with
regards to the NPU DMA transaction.

GCC and armclang uses different uint32_t types which makes it impossible
to use standard format specifiers to satisfy both compilers. Move to
inttypes.h macros to handle it in a portable way.

Bit [2] in CMD register is used to enable clock off using
clock q-interface and enable the master clock gate. Bit [3] is
used to enable power off using power q-interface.
The clock_q_enable bit is set when putting the Ethos-U into run
state.
The power_q_enable bit is set to 0 when running the command stream
and set to 1 after command stream has finished running.

Moving the alignment checks for command stream and base addresses
to handle_command_stream(). This is done so that applications which
directly call ethosu_run_command_stream(), and don't have command
stream & base addresses properly aligned can still run the command
stream.

Also check that the command stream address and base address are
aligned to 16 bytes. Return error in case they are not correctly
aligned.
