Daniel DeGrasse 9d7a3fb647 drivers: flash: flash_flexspi_nor: support SFDP probe
Support SFDP probe in flexspi nor driver. This probe will allow the
flash driver to dynamically configure quad spi flashes for 1-4-4 mode,
expanding the flash chips supported with this driver.

The following data is read from the SFDP header:
- quad enable method
- fast read command (1-4-4 is maximum supported)

Fixes #55379

Daniel DeGrasse f81113e948 drivers: clock_control: add support for FlexSPI reclock on NXP iMX RT10XX
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.

Daniel DeGrasse 9a63f39cd8 drivers: memc: update interface of memc flexspi driver for multi device
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)

Jeppe Odgaard cd59e74412 drivers: memc: add update clock function
Add a function to update the flexspi bus clock. This is
needed when write operations are done to the hyperflash.

Gerard Marull-Paretas fb60aab245 drivers: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Nicolai Glud 81cdf7a455 drivers: flash: added flexspi hyperflash.
This enables accessing the hyperflash through the flash api.

Added a feature to memc_mcux_flexspi that waits for flexspi bus to be
quiet.

Pieter De Gendt acca3c126c mcux flexspi: move bus driver to drivers/memc
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.
