This is the nominal speed according to the TRM, and using higher
root clock gives more frequency selections (possible dividers) for
the SD card clock configuration.

- Change the board's sd-card speed configuration to just specify the wanted frequency
- Calculate the proper divisors in the driver
- If the sd card frequency exceeds 25 MHz, set the card to high-speed mode
This makes it easier to adjust the operating speed of the sd cards and fixes an error
where cards are being operated in standard mode at over 25MHz speeds. If the speed
is higher than 25MHz, the card needs to be set into high-speed mode.

All combinations of CONFIG_IMX9_USDHC_DMA and CONFIG_ARM64_DCACHE_DISABLE
are valid. Only the required alignment of the DMA buffers are different,
If the cache is enabled, cacle-line aligned buffers need to be used.
Otherwise, the USDHC DMA alignment requirement is just 32-bits.

This commit adds support for PlantUML to the Documentation build
process. UML diagrams can be written in PlantUML syntax and then
rendered during the build process. Version control no longer needs to
track these UML diagrams as images, and we can modify them easily.

Add packed attribute to lzf header structs to prevent the compiler
from optimizing lzf_magic array initialization into wider store
instructions (e.g. st.h), which can cause misaligned access
exceptions on architectures that do not support unaligned memory access.

The internal implementation of `file_mq_receive` did not allow
receiving a message from an interrupt handler. Although it is not
possible to wait for a message in an interrupt context, it is
perfectly possible to retrieve already-existing messages from the
message queue. This commit modifies file_mq_timedreceive_internal
to enable checking the message list and, if no messages exist, it
returns immediately. This enables receiving any existing messages
in an interrupt context.

Fix three issues in the STM32H7 FDCAN SocketCAN driver:
1. Clock configuration: Allow board.h to override STM32_FDCANCLK.
Previously the driver hardcoded STM32_HSE_FREQUENCY, ignoring
any board-specific clock configuration.
2. ILS register bug: Fix putreg32 call that was writing FDCAN_ILS_TCL
constant instead of the computed regval, causing interrupt routing
issues.
3. Extended ID filter size: Increase n_extid from 64 to 128. Despite
the reference manual (RM0433) suggesting 64 max, testing shows
that 128 is required for reliable extended ID frame reception.
With 64, some extended ID frames were silently dropped.

- Add support for the MR-NAVQ95 which is an open-source development
board designed for mobile robotics applications.
- Utilizes the NXP i.MX95 processor M7 core
- Configurations:
'nsh' A minimal configuration that only enables nsh shell
on a UART
'rpmsg' This configuration is similar to nsh but in addition
it offers the Remote Processing Messaging (RPMsg) service to
enable heterogeneous inter-core communication.

Fix incorrect flag handling and string escaping in the `make host_info`
diagnostic target.
Previously, CFLAGS, CXXFLAGS, and LDFLAGS were passed in a form that caused
improper splitting and quoting, which resulted in malformed output and
incorrectly escaped configuration values such as CONFIG_APPS_DIR.
This change ensures that:
- Compilation flags are passed as proper shell strings
- Flags are split correctly using shlex
- Configuration values are escaped exactly once when generating sysinfo.h
- Parsed output matches the contents of the .config file
This change affects diagnostic output only and does not modify the NuttX
build process or generated binaries.
