Add support for initializing the FLEXSPI when using a flash attached to
the FLEXSPI for XIP. This option is guarded behind a Kconfig, as
enabling it is dangerous and requires special care be taken by the user
to ensure that the configuration of pins and FLEXSPI settings will not
break support for reading the attached flash, as this will break XIP
support.

When multiple devices are used, the FLEXSPI will place their address
spaces sequentially (based on the chip select port used). Additionally,
each device must use different sections of the FLEXSPI LUT table.
Fix the following calculation issues with multi-device usage:
- correct calculation of LUT sequence indices for AHB commands
- correctly add address and sequence offset when submitting FLEXSPI IP
transfer

Add support for reclocking the FlexSPI on NXP iMX RT10XX. This
functionality requires an SOC specific clock function to set
the clock rate, since the FlexSPI must be reset directly
before applying the new clock frequency.
Note that all clock constants are defined in this commit, since the
memc flexspi driver now depends on a clock node being present.

Update interface of memc flexspi driver to better handle multiple
devices. Previously, using multiple devices on one FlexSPI bus would
require the user to configure each device to install its command table
(referred to as a LUT table by the driver) at an offset, so that it did
not overlap with other devices on the bus.
This commit changes the interface of the memc flexspi driver to instead
configure the LUT and flash device in one call. This allows the memc
driver to record the port each LUT sequence is used with, so that
future FlexSPI transfer requests can have their LUT offsets adjusted
based on the target port (which will correspond to a target device)

The NXP S32 QSPI controller acts as an interface to up to two serial
flash memory devices, each with up to eight bidirectional data lines,
depending on the platform. It is based on a LUT enginee to interface
through commands with different memory types including flash NOR and
Hyperram.
This patch adds support for the QSPI in S32K344 which supports a single
memory device (side A) with up to four bidirectional data lines and SDR
only. Nevertheless, the memory controller is implemented flexible enough
to be extended to support more feature-rich QSPI blocks.

Update flexspi driver init priority to be the
memc driver init priority. This fixes a bug where
the flexspi flash drivers on i.MX RT platforms were
being initialized before the flexspi memc driver.
Since those flash drivers depend on the flexspi
spi bus controller being initialized, the flash drivers
would fail to initialize and cause runtime failures.

Only relocate memc driver when CONFIG_FLASH=y.
CONFIG_FLASH_MCUX_FLEXSPI_XIP previously was dependent on
CONFIG_FLASH, but the scope of this Kconfig has changed.
Due to this, the memc driver now must have two checks, as it should not
relocated when the driver is being used for a memory controller that does
not expose the flash driver interface.
Since the NXP HAL also relocates the underlying FlexSPI driver
using a similar check, it is updated in this commit as well.
