nor: boot the split layout on gk7202v300 and gk7605v100

[widgetii]

This enables the split NOR layout from #18 on the other two SoCs of the gk7205v200 kernel family:

• CONFIG_FIT, CONFIG_SHA1 and CONFIG_OPENIPC_NOR_FIT_SPLIT in xm72020300_config and xm76050100_config;
• verify=n set before openipc_helper(), so the FIT path can drop it and check the hashes.

A uImage at the kernel offset keeps the fixed slots, exactly as before.

Size: NOR images are 222 KB (gk7202v300) and 216 KB (gk7605v100), against the 256 KB limit.

Build-tested only: I have no gk7202v300 or gk7605v100 board. The same code is verified on GK7205V200 and GK7205V300, both running the published g7e52056f image from flash.

Enable split NOR FIT boot on gk7202v300 and gk7605v100

✨ Enhancement ⚙️ Configuration changes 🕐 10-20 Minutes

AI Description

• Enable hashed split-NOR FIT boot on gk7202v300 and gk7605v100.
• Preserve fixed-slot uImage boot while allowing FIT hashes to be checked.
• Both images fit the 256 KB boot partition; hardware boot remains untested.

High-Level Assessment

Extending the existing split-NOR path through board configuration and initialization order is appropriate. A shared-board refactor would add scope without changing the boot behavior.
