SHIM Nordic modification for the ADC driver controlling the SAADC peripheral. Replaced HAL based implementation in favor of nrfx driver. As a next step, it is planned to implement a feature that will allow the peripheral SAADC timer to be used for sampling, and for this it is necessary to use the nrfx driver in this SHIM. This will allow more accurate and faster sampling than the kernel mechanism currently provides. Signed-off-by: Jakub Zymelka <jakub.zymelka@nordicsemi.no>
