doc: releases: 4.0: Add release notes for Flash and Storage

  * Fixed SPI NOR driver issue where wp, hold and reset pins were incorrectly initialized from

    device tee when SFDP at run-time has been enabled (:github:`80383`)

  * Added :kconfig:option:`CONFIG_SPI_NOR_ACTIVE_DWELL_MS`, to the SPI NOR driver configuration,

    which allows setting the time during which the driver will wait before triggering Deep Power Down (DPD).

    This option replaces ``CONFIG_SPI_NOR_IDLE_IN_DPD``, aiming at reducing unnecessary power

    state changes and SPI transfers between other operations, specifically when burst type

    access to an SPI NOR device occurs.

  * Added :kconfig:option:`CONFIG_SPI_NOR_INIT_PRIORITY` to allow selecting the SPI NOR driver initialization priority.

  * The flash API has been extended with the :c:func:`flash_copy` utility function which allows performing

    direct data copies between two Flash API devices.

  * Fixed a Flash Simulator issue where offsets were assumed to be absolute instead of relative

    to the device base address (:github:`79082`).

* GNSS

* GPIO

    from version 2.8.1, the last module update, up to and including

    the released version 2.9.3.

  * LittleFS: Fixed an issue where the DTS option for configuring block cycles for LittleFS instances

    was ignored (:github:`79072`).

  * LittleFS: Fixed issue with lookahead buffer size mismatch to actual allocated buffer size

    (:github:`77917`).

  * FAT FS: Added :kconfig:option:`CONFIG_FILE_SYSTEM_LIB_LINK` to allow linking file system

    support libraries without enabling the File System subsystem. This option can be used

    when a user wants to directly use file system libraries, bypassing the File System

    subsystem.

  * FAT FS: Added :kconfig:option:`CONFIG_FS_FATFS_LBA64` to enable support for the 64-bit LBA

    and GPT in FAT file system driver.

  * FAT FS: Added :kconfig:option:`CONFIG_FS_FATFS_MULTI_PARTITION` that enables support for

    devices partitioned with GPT or MBR.

  * FAT FS: Added :kconfig:option:`CONFIG_FS_FATFS_HAS_RTC` that enables RTC usage for time-stamping

    files on FAT file systems.

  * FAT FS: Added :kconfig:option:`CONFIG_FS_FATFS_EXTRA_NATIVE_API` that enables additional FAT

    file system driver functions, which are not exposed via Zephyr File System subsystem,

    for users that intend to directly call them in their code.

  * Stream Flash: Fixed an issue where :c:func:`stream_flash_erase_page` did not properly check

    the requested erase range and possibly allowed erasing any page on a device (:github:`79800`).

  * Shell: Fixed an issue were a failed file system mount attempt using the shell would make it

    impossible to ever succeed in mounting that file system again until the device was reset (:github:`80024`).

* Task Watchdog

* POSIX API

Known Issues

============

- :github:`71042` stream_flash: stream_flash_init() size parameter allows to ignore partition layout

- :github:`67407` stream_flash: stream_flash_erase_page allows to accidentally erase stream
