Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

This is done to support the idiomatic way of performing flush
operations, where the caller might not have access to the proper data
pointer. Also, there is no reason why reading from address 0 should
not be allowed.

With addition of flash_parameters structure, and supporting API call
to retrieve it, it is no longer needed to store write_block_size as
a part of flash_driver_api and it should be part of flash_parameters.

stream_flash_bytes_written() returned number o bytes physically
written to the flash. This number might be bigger than the requested
number as is aligned to the device write-block-size.
stream_flash_bytes_written() should return number of bytes
written requested by the user.

On buffer flush request it is very probably that write buffer
contains amount of data which is non write-block-size aligned.
Flash memory need to be write at minimal by write-block-size chunks.
This patch addresses mechanism which ensure such behavior by adding
missing bytes.
fixes#25471
streamer buffer size should be multiple write-block-size of
the flash device in order to avoid unaligned flash write
request.

This library supports stream writes to flash with
optinal progressive erase.
This module is a direct copy of the functionality found in
subsys/dfu/img_util/flash_img.c
