Avoid clock related interrupts before jumping into the first image. Safe
to disable as the first application will enable the clock/timer again
once booted.

The bootloader is just using Zephyr as a HAL and doesn't require
thread scheduling. Build Zephyr in single-threaded mode and gain
some footprint savings.

Bluetooth is enabled by default with some boards, so just make sure that
it gets disabled here to avoid having a large bootloader firmware.

Make it generic and let the SoC itself handle the FLASH driver support
as part of the Zephyr build system.

The Zephyr build systems makes some assumptions about the directory
layout, and encounters problems if the necessary path contains "../..".
To help this, place the zephyr directory next to the bootutil directory
so that the Makefile can just refer to "../bootutil". This keeps all of
the build artifacts under the proper top-level directory.
