Add new devicetree bindings for F4 and L1 series for configuration of
block size used in flash write operations.
Allow byte-size write operations in `flash_stm32f1x.c`. This file is
being shared between F0, F1, F3, L0 and L1 series. L0 and L1 series
allows for single byte writes.

This commit adds layput page cells to the atmel sam flash
controller and the flash node. These allow for describing
the actual flash page layout of each soc, allowing the
flash driver to fully utilize the capabilities of the
flash.
With this update, we unlock the following capabilties:
- utilize 2048 erase block size for small sectors
- utilize 16384 erase block size for large sectors

Add support for flash NOR memory devices on a NXP S32 QSPI bus. The
driver uses a fixed LUT configuration assuming a default standard page
size and erase types, and allows to select between multiple read/program
instructions/modes. It is also possible to read the flash device
characteristics from the device at run-time as long as the memory is
JESD216 compatible, providing more flexibility.

Most available AT45 flash chips have their first two sectors shorter
than the consecutive ones. Usually, the first sector is marked as 0a
and has its size equal to eight pages (one block) and the second one
(usually 0b) is the complement to the size of a regular sector.
This commits modifies the driver so that erasing of these first two
sectors is performed correctly. This modified behavior is configurable
with a new DT property so that it is still possible to also use legacy
AT45 chips that do not feature such sector split. Such legacy chips
usually also do not support the chip erase and sector erase commands,
so two more DT properties are introduced to cover that.

The max-erase-time property was introduced for the STM32 flash driver,
but it was inserted as an optional property in the generic
soc-nv-flash binding which is used by other SoCs.
Make it a required property in a new st,stm32-nv-flash binding
instead, since it is at present a vendor specific property.
Update the DTS files accordingly. Keep the existing "soc-nv-flash"
value in the compatible list in each case, so that DT_HAS_COMPAT(...
soc_nv_flash) tests on these nodes will still succeed, but put it
after a newly added "st,stm32-nv-flash" compatible, so that the
SoC-specific binding will be used as it is discovered first by the DT
tooling.

Some SPI NOR devices, particularly Atmel and SST, power-up with block
protect bits set in the status register. These bits must be cleared
before any erase or program operation can succeed. However, blindly
clearing bits in SR is wrong as some of these are non-volatile and
control chip behavior, including quad-enable.
Add a devicetree flag to identify device-specific BP bits in the status
register that should be cleared on startup only for devices that need
them, and when set do the clear during initialization.

This driver emulates a EEPROM device in flash.
Reworked implementation with modified flash layout.
The emulation represents the EEPROM in flash as a region that is a
direct map of the eeprom data followed by a region where changes to
the eeprom data is stored. Changes are written as address-data
combinations. The size of such a combination is determined by the
flash write block size and the size of the eeprom (required address
space), with a minimum of 4 byte.
The eeprom page needs to be a multiple of the flash page. Multiple
eeprom pages is also so supported and increases the number of writes
that can be performed.
The eeprom size, pagesize and the flash partition used for the eeprom
are defined in the dts. The flash partition should allow at least two
eeprom pages. For fast read access a rambuffer can be enabled for the
eeprom (by setting the option rambuf in the dts).
