add NanoPi R76S support for edge kernel builds

[SuperKali]

Description

This PR contains the rewritten DTS to enable current mainline implementations for the NanoPi R76S board, allowing kernel edge support.

How Has This Been Tested?

Learning: Not all Armbian boards support all kernel versions (legacy, current, edge). Some boards may only support specific kernel versions due to hardware limitations or lack of mainline support, which is why their KERNEL_TARGET contains only the supported options (e.g., just "legacy").

Learning: In Armbian build system configuration files like config/sources/families/*.conf, KERNELSOURCE is explicitly declared when using unofficial or 3rd party kernel repositories (like the "dev" branch using https://github.com/apritzel/linux), but can be omitted when using the standard mainline kernel (like the "edge" branch) since it will fall back to the default mainline source.

Timestamp: 2025-08-02T05:46:10.664Z
Learning: In the Armbian build system, the modern recommended approach for kernel configuration is to use the kernel-config command via "./compile.sh BOARD=boardname BRANCH=branchname kernel-config" instead of the deprecated KERNEL_CONFIGURE=yes flag. This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.

Timestamp: 2025-06-25T03:40:52.109Z
Learning: In Armbian build system configuration files like config/sources/families/*.conf, when KERNELSOURCE is not explicitly declared in a case branch, the system falls back to a default KERNELSOURCE value, so missing KERNELSOURCE declarations are not critical issues.

Timestamp: 2025-05-05T12:35:07.143Z
Learning: For the interactive kernel selection in Armbian, KERNEL_MAJOR_MINOR and KERNEL_DESCRIPTION are parsed from family.conf but deliberately not set as environment variables to avoid potential interference with other parts of the build system.

5-5: Edge support via KERNEL_TARGET looks good

Adding edge aligns with the PR goal. No extra KERNELSOURCE needed; mainline fallback will handle edge for rk35xx.
