This patch add basic building blocks for nrf9P60. It also includes a secure bootloader which forwards all possible peripherals that are user selectable to become non-secure. After configuring Flash, RAM and peripherals the secure bootloader will jump to the non-secure domain where MicroPython is placed. The minimum size of a secure boot has to be a flash block of 32Kb, hence why the linker scripts are offsetting the main application this much. The RAM offset is set to 128K, to allow for later integration of Nordic Semiconductor's BSD socket library which reserves the range 0x20010000 - 0x2001FFFF.
