Adds syscalls: - ALLOCATE_AREA - DEALLOCATE_AREA - WRITE_DATA - READ_DATA and code to access the filesystem and the flash over SPI. Based on original work by Daniel Jobson <jobson@tillitis.see> for these files: - auth_app.[ch] - flash.[ch] - spi.[ch] - partition_table.[ch] - rng.[ch] - storage.[ch] which are used with small changes to integrate with the new syscall method.
