Move PMU functions from pmu_ethosu.h to ethosu_pmu.c

This change is done as a prerequisite to be able to set
base address for NPU through ethosu_init(). So instead of using
a mamory mapped struct we use the same functions to read/write
PMU registers as the rest of the ethos-u driver.

Ethos-u Core Driver

This repository contains a device driver for the Ethos-u NPU.

Building

The source code comes with a CMake based build system. The driver is expeced to be cross compiled for any of the supported Arm Cortex-m CPUs, which will require the user to setup a custom toolchain file.

The user is also required to define CMAKE_SYSTEM_PROCESSOR for the target CPU, for example cortex-m55+nodsp+nofp. This can be done either in the toolchain file or on the command line.

$ mkdir build
$ cd build
$ cmake .. -DCMAKE_TOOLCHAIN_FILE=<toolchain> -DCMAKE_SYSTEM_PROCESSOR=cortex-m<nr><features>
$ make
