Replace the hardcoded MSPI_XFER_LITTLE_ENDIAN value in
MSPI_DEVICE_CONFIG_INIT() with DT_ENUM_IDX_OR(), so the
init_cfg endian field is driven by the mspi-endian property
of the device node when present, falling back to big-endian
when the property is absent.

XIP in Zephyr is a software configuration concept (CONFIG_XIP). The MSPI
feature gated by MSPI_XIP only memory-maps the device into the SoC
address space; the mapped region can be used for plain data access as
well as code execution. Rename the feature to MEMMAP to reflect what it
actually does:
- CONFIG_MSPI_XIP -> CONFIG_MSPI_MEMMAP
- CONFIG_FLASH_MSPI_XIP_READ -> CONFIG_FLASH_MSPI_MEMMAP_READ
- struct mspi_xip_cfg -> struct mspi_memmap_cfg
- enum mspi_xip_permit / MSPI_XIP_READ_* -> mspi_memmap_permit /
MSPI_MEMMAP_READ_*
- mspi_xip_config() -> mspi_memmap_config(), driver API entry
xip_config -> memmap_config
- MSPI_XIP_CONFIG_DT{,_INST,_NO_CHECK} -> MSPI_MEMMAP_CONFIG_DT{,...}
- MSPI_XIP_CFG_STRUCT_DECLARE / MSPI_XIP_BASE_ADDR_{DECLARE,INIT} ->
MSPI_MEMMAP_*
- devicetree property xip-config -> memmap-config
Vendor HAL symbols (am_hal_mspi_xip_*) and DesignWare register names,
where XIP is the hardware documentation terminology, are unchanged.
The MSPI API is experimental, so no deprecated aliases are provided;
a migration guide entry is added in a separate commit. Add missing
Doxygen comments on new API symbols. Add missing SPDX header to the
nrf54h20dk code_relocation_nocopy overlay touched by this rename.

any supported rate works without per-rate constants. Add the devicetree

Generic MSPI driver for the ISSI IS66/67WV Serial PSRAM family
(both wrapped-burst WVS and continuous WVR variants).
Implements MEMC read/write for bus-transaction access via MSPI.
When CONFIG_MSPI_XIP=y and xip-config is present in DT with
enable=true, also implements get_mem_base so the memcpy path
is used automatically on controllers with a memory-mapped
aperture.

Implement a device driver for XSPI manager.
This allows to define the xspi controllers configuration that should
be applied towards the xspi IO ports:

- Swapped

Since its configuration has impact on final application location and
implies the deactivation of xspi clocks, it should be run only at fsbl

Use STM32_CLOCK_INFO(), STM32_DT_INST_CLOCK_INFO(),
STM32_CLOCK_INFO_BY_NAME() and STM32_DT_INST_CLOCK_INFO_BY_NAME()
helper macros in STM32 drivers.
Using these macros ensure the clock division factor is properly
populated according to DT information. Prior these changes some
drivers only got the bus and bits position information and missed
the clock division information which is fine only when this division
factor information is 0.

Enable this kconfig setting to force using a specific raw value for the
OVRDVAL field in the DLLCR registers.
This option gives more granularity than the 'data-valid-time' field in
the dts. The unit of 'data-valid-time' is nanoseconds while the unit of
OVRDVAL are raw delay cells.
Normally the 'data-valid-time' on any 'nxp,imx-flexspi-device' device
will set the OVRDVAL and OVRDEN fields in the DLLCR register
but works only when the 'rx-clock-source' is configured to '#0 External
input from DQS pad' and the frequency <= 100MHz.

In the original HAL, sl_si91x_psram_init() and sl_si91x_psram_uninit() were
also in charge of configuring the pinctrl and the clocks. A workaround
have been introduced to avoid change in pinctrl but they still changed the
clock configuration.
We definitely need to expose the clock configuration to Zephyr users. The
HAL has been patched to split the sl_si91x_psram_*init() function in
smaller pieces. So it is possible to configure the devic without changing
the clock or the pinctrl. Let's use these new functions.
