This fixes an issue found on stm32f3 where newtmgr after writing an odd
sized packet, would hardfault on the next write due to trying to write an
odd address which is not valid on stm32f3 flash.

This patch introduced serial bootloader functionality ported
from mynewt targets tree.
For achieving this following changes were applied:
- Modified boot_serial module for using, zephyr-os modules
(crc driver, mbedtls-base64 library) and the zephyr serial adapter module
introduced recently.
- Added service of boot serial recovery mode to main.
- Adapted the input parser to using static buffers.
Default serial-boot-pin configuration was added for nrf52_pca10040
and nrf52840_pca10056 boards.
