STM32 : script to generate PeripheralPins.c for new target addition

$ python genpinmap_mbed.py -h
usage: genpinmap_mbed.py [-h] [-l | -b | -m xml | -t HW]

Script will generate PeripheralPins.c thanks to the xml files description available in
STM32CubeMX directory defined in 'cube_path.json':
        C:\Program Files (x86)\STMicroelectronics\STM32Cube\STM32CubeMX\db

optional arguments:
  -h, --help          show this help message and exit
  -l, --list          list available mcu xml files description in STM32CubeMX
  -b, --boards        list available boards description in STM32CubeMX
  -m xml, --mcu xml   specify the mcu xml file description in STM32CubeMX to use (use double quotes).
                         Parameter can be a filter like L496 if you want to parse all L496 chips (-m STM32 to parse all).
  -t HW, --target HW  specify the board file description in STM32CubeMX to use (use double quotes).
                         Parameter can be a filter like L496 (only the first file found will be parsed).

Once generated, you have to check and comment pins that can not be used (specific HW, internal ADC channels, remove PWM using us ticker timer, ...)
