These changes mostly focus on creating a better structure
for the driver. Creating a better separation between driver
and device(s).
A short summary of what this commit contains:
- Move driver specific defines from device to driver
- Prefix device functions with ethosu_dev
- Remove device specific register access' from driver
- Remove device specific debug/dump functions
- Add function prototypes for weak functions
- Remove legacy ARM_NPU_STUB support
- Rename ethosu_device.c to ethosu_device_u55.c
- Remove redundant irq handler prototype
- Remove (deprecated) hardcoded instance ethosu_drv
- Simplify versioning API
Split driver version and hardware version/information so
that driver version can be queried without a driver instance.
- Improve and simplify logging
Make warning the new default severity level to print and
reduce severity levels to:
err
warning
info
debug
- Add severity prefix to log lines. Error messages print file
and line number, debug messages print function by default.
- Clarify some log messages
- Small optimizations and bugfixes

Removing the ASSERT() makro using assert() instead. assert() is better
controlled with the NDEBUG define.
Using uintptr_t instead of uint32_t * for the NPU base address. This
saves a division by 4 in the register read and write functions.

---ethosu_driver---
Modified: Declarations for the driver interfaces to support multiNPU (takes *drv)
Added: ethosu_register_driver(...) to allow for a specific NPU driver to be instantiated
Added: ethosu_deregister_Driver(...) to allow for a specific NPU driver to be de-registered
Added: ethosu_reserve_driver(...) to reserve & return the first NPU driver instance available
Added: ethosu_release_driver(...) to release a specific NPU driver instance and make it available again
Added: *registered_drivers - A static linked list of drivers ready be used
---ethosu_pmu---
Modified: Declarations for pmu interfaces to support multiNPU (takes *drv)
---ethosu_device---
Modified: Resolved a circular include dependency (Remove include and add ETHOSU_PMU_NCOUNTERS macro)

Storing PMU counters in shadow variables, in case the PMU was powered
off or soft reset.

The ETHOSU is soft-reset only if the previous job failed or if
the current privilege level is not user or if the current security
level is not secure.
