Rename the application-owned LLCC68 devicetree compatible to semtech,llcc68-weihua so Zephyr releases with a native semtech,llcc68 binding can coexist with this custom driver module. Use the registered semtech vendor prefix and a project-specific device suffix; DT_DRV_COMPAT maps to semtech_llcc68_weihua.
