Let boards only define the port and pin number of each LEDs. The common definitions in `stm32_leds.h` will provide `LED<x>_ON`, `LED<x>_OFF`, `LED<x>_TOGGLE`, `LED<x>_PIN`, `LED<x>_MASK` and `LED<x>_PORT`. In addition to code de-duplication, this also makes it easier to use LEDs in GPIO LL, which can be beneficial for super low overhead debugging output - e.g. when a bug is timing sensitive and `DEBUG()` would spent to much time for stdio to reproduce a bug.
