Read the MCUboot-Espressif load header at hdr_size and use it to populate entry point plus IROM/DROM mapping parameters.
This replaces the incorrect esp_image_header_t parsing path in board_boot_image() for this flow and aligns with the image layout used by MCUboot/nxboot on ESP32.

This commit fixes the style issues in the ESP32 boot image implementation:
- Reset esp32_partition.c to upstream master to fix extensive formatting issues
- Add minimal OTA_IMG_GET_OFFSET ioctl case with correct NuttX style
- esp32_boot_image.c and partition.h already fixed in previous commits

- 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.

When the VIRTIO_RPMSG_F_CPUNAME feature is not negotiated, the driver
previously would crash due to DEBUGASSERT. This commit adds support
for a fallback mechanism:
1. Add rpmsg_virtio_probe_cpuname() API that accepts an optional cpuname
parameter to be used when VIRTIO_RPMSG_F_CPUNAME is not available.
2. Modify rptun driver to pass the cpuname from rptun device config
to rpmsg_virtio_probe_cpuname().
3. Refactor rptun device register/unregister to prioritize RPMSG device
handling before other virtio device types.
This ensures the system works correctly in scenarios where the remote
side does not support the VIRTIO_RPMSG_F_CPUNAME feature.

With CONFIG_PAGING enabled and the RISC-V SV39 MMU active, the page fault
handler incorrectly tracked page table levels: `ptprev` pointed to the L1
page table while `ptlevel` indicated L2. This inconsistency caused faulty
virtual address resolution.
This commit fixes the traversal logic to ensure consistent level tracking
across all three page table levels (L1–L3), enabling reliable page fault
handling and on-demand paging.
Additional changes:
- Set PGT_L3_SIZE to 2048 to enable mapping up to 8MB of address space.
- Update knsh_paging config to avoid crashes caused by excessive memory
alignment requirements.
- Add knsh64_paging config to verify this commit works as expected.

This commit refactors nxsched_waitpid() by extracting the core waiting logic
into a separate waittcb() helper function. This change significantly reduces

functionality and improving code maintainability with better separation of
concerns between initialization and wait handling logic.

Add comprehensive documentation for the Vhost framework, which serves
as the VirtIO backend implementation in NuttX for cross-core communication.
The documentation includes:
- Overview and comparison with Linux Vhost and QEMU VirtIO Device
- Three-layer architecture (Service, Framework, Transport)
- Driver/Device registration and matching workflow
- Source code directory structure
- Complete API reference (data structures, core APIs, macro APIs)

Move common virtio inline functions (virtqueue_kick_lock, virtio_malloc_buf,
virtio_zalloc_buf, etc.) from CONFIG_DRIVERS_VIRTIO guard to CONFIG_OPENAMP
guard. This allows vhost drivers to reuse these helper functions without
requiring the full virtio driver framework.
The virtio_driver structure and driver registration APIs remain under
CONFIG_DRIVERS_VIRTIO as they are specific to virtio device drivers.
