ci: build and smoke-test the XM530/XM550 SPI NAND images

[widgetii]

openipc-xm now builds SPI NAND images for xm530/xm550 (#16). This PR:

• builds them with kinds: "nor nand", checking each NAND image against the 768 KiB boot partition;
• adds a NAND qemu_smoke leg for each. The leg lays the image into a raw 128 MiB SPI NAND (2048+64-byte pages) and boots it twice through qemu-hisilicon's NAND model (binman: Fix replacing FIT subentries u-boot/u-boot#152). It passes on the autoboot prompt and fails if the second boot can't load the env the first boot saved in NAND;
• marks the NAND images unverified on silicon in the README. They follow a guess at how the XM530 boots from SPI NAND, and the qemu model implements the same guess.

Checked locally: all five smoke legs (3 NOR, 2 NAND) pass as written against qemu-hisilicon master. This PR's own run builds the current openipc-xm.

AI Description

• Build XM530/XM550 NAND images and enforce the existing 768 KiB boot-partition limit.
• Add two NAND smoke legs that check boot and saved-environment persistence across restarts.
• Mark NAND images unverified on silicon because QEMU shares their undocumented boot assumption.

High-Level Assessment

Extend the existing build matrix and shared two-boot smoke test rather than create a separate NAND workflow. This preserves the current artifact and release gates while isolating the flash-specific setup; the documentation appropriately limits QEMU results to the model's unverified hardware assumption.

Build XM530/XM550 NAND images and add NAND smoke legs

• Enables NAND alongside NOR for XM530/XM550, activating the existing 768 KiB NAND partition check. Adds a smoke leg per NAND image that prepares raw page-and-spare NAND media, boots QEMU twice, and uses the existing prompt and environment checks.
