* updated submodule
* usb_serial: populate usb_device before usb_run. Upstream now leaves the global usb_device zero-initialized and expects hackrf_usb.c to memcpy a per-board const into it. We don't link hackrf_usb.c, so do the memcpy here. Also flip control_in to enable_zlp=true to match the new endpoint API.
* baseband: derive IS_* board defines from BOARD. Upstream moved platform IS_* macros from platform_detect.h to cmake. Set them per BOARD here since we don't include platform-detect.cmake. Drop the duplicate clkin.c entry.
* sd_over_usb: drop duplicate driver objects, fix setup callback. Upstream now defines i2c0/i2c1, spi_bus_ssp0/1, sgpio_config and rf_path in the common driver files, so stop redefining them here and patch the runtime fields in pin_setup() instead. Update si5351c_reset_pll() call to the two-arg form. Replace the no-op transceiver_usb_setup_complete stub with one that delegates to usb_setup_complete.
* sd_over_usb: populate usb_device before usb_run. Same fix as the application side: memcpy a const template into usb_device before usb_device_init/usb_run, otherwise the descriptor pointer is NULL. Also pass enable_zlp=true on control_in to match the new endpoint API.
* fix unicode in comment
* remove lz4 bufs reservation in M0
