This Kconfig is moved to the soc level since it determines
the flexspi clock initialization for XIP.

It's useful for RAMABLE_REGION to have a uniform name when
CODE_DATA_RELOCATION is supported, because otherwise the build system
needs to be aware of how the region name differs between architectures.
Since architectures tend to prefer one of 'SRAM' or 'RAM' for that
region, prefer to use 'RAM' as the more general term.

The binding 'nxp,lpc-iap' is no longer used, which is confirmed
by running:
$ find ${ZEPHYR_BASE}/dts/arm/nxp -type f | egrep -e '\.dts(i)*$' | \
xargs grep -nH nxp,lpc-iap
Changes in this commit:
- remove DT_HAS_NXP_LPC... in drivers/flash/Kconfig.mcux
- remove schema file for nxp,lpc-iap

The lpc and mcux drivers' DRV_COMPAT is updated for the new bindings
introduced in the previous commit. The drivers' Kconfig files also
reflect this change (DT_HAS_ENABLED_NXP_...).
The SoC device trees are updated with the new bindings

Update flash drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

- The MX25UM51345G flash is connected to FLEXSPI PortA for
mimxrt595_evk.
- Updated flexspi_mx25um51345g driver to support DTR OPI mode.
- Tested with tests/drivers/flash.

Do not default FLASH_MCUX_FLEXSPI_XIP to enabled when code is not
located in flash, this will cause issues if code is executing from ITCM,
as the zephyr_code_relocate macro will relocate the flash driver code
into itcm, and overwrite the zephyr image.

This enables accessing the hyperflash through the flash api.
Added a feature to memc_mcux_flexspi that waits for flexspi bus to be
quiet.

This feature prevents issues when trying to write data to the flash
device that is located on or addressed at the same flash device.
An example is the mcuboot logic that writes a magic number to
the secondary partition header.

This change allows writing to the flash while running in XIP mode,
and enables mcuboot or NVS settings to be used on i.MX RT socs.

Initially the flexspi device only supported a flash driver for
external NOR flash. As the controller supports HyperBus devices,
which can be either volatile or non-volatile, the driver iss moved
to drivers/memc.

Added selection of MPU_ALLOW_FLASH_WRITE.
Using a flash driver while MPU is enable without
this option on doesn't make sense at all.

Introduces a new flash driver for the FlexSPI peripheral on i.MX RT
SoCs. The hardware provides a flexible sequence engine (LUT) that
supports various types of external devices, including serial NOR flash,
serial NAND flash, HyperBus (HyperFlash/HyperRAM), and FPGAs. It
supports up to four connected devices in single/dual/quad/octal modes
and provides memory-mapped read/write access to these devices through
the AHB bus.
The driver implementation consists of a shared controller for each
FlexSPI peripheral instance, and protocol-specific device drivers for
each external device. The controller provides a private interface for
multiple devices to access the FlexSPI peripheral registers. FlexSPI
devices provide the public flash driver interface to applications or
subsystems like storage or flash file systems; they also provide
protocol-specific LUT sequences to the controller.
Currently the only device type supported is QSPI NOR flash, but other
types like HyperFlash will be added later.
XIP is not yet supported, as this requires additional work to relocate
code to RAM and managing interrupts.

LPC55xxx SoCs don't allow reading erased areas, the flash memory
controller (FMC) will trigger an ECC error for that area. To prevent
reading unwritten areas the low level FMC command of margin checking is
used, this will fail if the area to be read is not correctly written
(margin_check) or area is erased (blank_check).
In the case of an erased page, we return dummy data so the application
can program that area.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

Adds a new config HAS_MCUX_FTFX to conditionalize the mcux flash driver
on socs that support it. Selects HAS_MCUX_FTFX on all kinetis socs
except kw40z, because even though this soc has the relevant hardware,
its CMSIS header file is not compatible with the mcux flash driver in
ext/.
This change also prevents enabling the mcux flash driver on lpc and imx
rt boards.

Cleanup the Kconfig code for the flash driver. Platform-specific
options should be in their own Kconfig files to be consistent and to
