Clean up the ARM core configuration only when
the CONFIG_MCUBOOT_CLEANUP_ARM_CORE is selected.
This involves cache and stack pointer limit registers.
Add also an MPU cleanup in platforms with the ARM MPU
supported.

Use <arch/arm/aarch32/cortex_m/cmsis.h> include instead of <zephyr.h> to
get access to Cortex-M CMSIS API. zephyr.h provides kernel API, does not
guarantee access to CPU internals.
Fixes: #699 "Building MCUBoot for Zephyr fails on multiple ARM boards"

This patch is needed as MCUBoot should be able to chain-load any
application, not only these built using zephyr.
Introduced cleanup on ARM core control register.
Might be required as for instance the application assumes
that it starts with thread mode configured as by default, not
according to zephyr-rtos configuration.
MCUBoot disables interrupt before application chain-load used
basepr register. This Patch introduce additional celenup on
NVIC register.
