dfu/flash_img: use flash_map instead of flash API

Browse source 
Patch introduces flash_map subsystem to operate on flash
image instead of direct operation using flash_driver API.
Changes allows to support operation on the image in any flash
device.

flash_map was not available when this subsystem was introduced.
