Since the release of X-LINUX-AI v6.0.1, AI support has been split between
devices with NPU and those relying solely on CPU. As a result, the Digi custom
patch to enable USB webcam support was no longer applied, because the
config_board_npu.sh script is now handled by the new config-npu.bb recipe.
This commit addresses the issue by introducing a new bbappend for config-npu,
ensuring that the webcam-related patch is correctly applied for NPU-enabled
platforms.
