Pull in raspberry-vanilla's AOSP17 device tree changes for rpi4 while keeping all PawletOS customizations (A/B partition layout, sepolicy, zram, TWRP recovery scaffolding, ALSA HDMI pre-warm, product/overlay structure) intact on top. Upstream changes absorbed: - AOSP17 audio HAL refactor (StreamAlsa split into StreamAlsaBase/ StreamAlsaMonoPipe, Utils.cpp -> UtilsAlsa.cpp, new Bluetooth/stub helper classes, libeffects AIDL rebuild via *_ndk_shared defaults) - API level 36 -> 37, FCM matrix level 202504 -> 202604 - QuickSettings tile default split (SystemUIRpiOverlay, ported into pawlet_rpi_common where this overlay now lives) - vendor_tracing_descriptors added to enforce-product-packages-exist - misc AOSP17 logging header switch (android-base/logging.h -> Log.h) Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
