mcu/nrf5340: Trust zone RAM clean update

RAM_SIZE was always taken from bps.h.
With trust zone in place it may be that the bootloader
had limited RAM assigned in linker scripts.
This may happen when MCU_BOOT_MEASURED_STARTUP is used.
This change clears only RAM that bootloader used.
If nothing special was done to linker scripts RAM size
will be the same as it used to be.
