boards: arm: nrf: add non-secure SRAM memory information in DTS

When we build Zephyr as Secure image on nRF340 Application MCU and nRF9160 SoC we would like to pass the information about the reserved memory area allocated to the Non-Secure images. The information may be needed to apply proper security configuration. We add a "chosen" node in board .dts file for this purpose.
