Add default app start and size limitations
Add default app start and size limitations

This commit introduces a default application start address (`0x1000`) and size limitation (`0xDF000`) to accomodate the Nordic USB bootloader.

The bootloader consists of a master boot record in flash from address `0x0` to `0x1000` and the actual bootloader application starting at `0xE0000` to the end of flash (`0x100000`). The bootloader enables firmware updates over USB using nRF Connect for Desktop.

More documentation regarding the open bootloader can be found here: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/ble_sdk_app_open_bootloader.html
