RIOT/sys/arduino/include/arduino_board_pins.h
Marian Buschsieweke 043e8cc88e
boards,sys/arduino: major clean up 
- Rename all `arduino_pinmap.h` to `arduino_iomap.h`
    - An empty `arduino_pinmap.h` that just includes `arduino_iomap.h`
      is provided for backward compatibility
    - Move all info from `arduino_board.h` into the new file as trivial
      macros, so that they can also be used outside of sketches
    - The new name reflects the fact not just pin mappings, but also
      other I/O features such as PWMs are mapped
- Drop all `arduino_board.h`
    - `arduino_board.h` and `arduino_iomap.h` now provide the exact
      same information, just in a different format
    - a generic `arduino_board.h` is provided instead that just
      uses the info in `arduinio_iomap.h` and provides them in the
      format the code in `sys/arduino` expects it
- Add fine grained features to indicate for mappings
    - availability of mappings for analog pins, DAC pins, PWM pins,
      UART devices, SPI/I2C buses to the corresponding RIOT
      identification can now be expressed:
        - `arduino_pins`: `ARDUINO_PIN_0` etc. are available
        - `arduino_analog`: `ARDUINO_A0` etc. are available
        - `arduino_pwm`: `ARDUINO_PIN_13_PWM_DEV` etc. are available
        - `arduino_dac`: `ARDUINO_DAC0` etc. are available
        - `arduino_uart`: `ARDUINO_UART_D0D1` or similar are available
        - `arduino_spi`: `ARDUINO_SPI_ISP` or similar are available
        - `arduino_i2c`: `ARDUINO_I2C_UNO` or similar are available
    - mechanical/electrical compatibility with specific form factors
      can now be expressed as features:
        - `aruino_shield_nano`: Arduino NANO compatible headers
        - `aruino_shield_uno`: Arduino UNO compatible headers
        - `aruino_shield_mega`: Arduino MEGA compatible headers
        - `aruino_shield_isp`: ISP header is available

This provides the groundwork to implement shield support as modules
that can rely on the I/O mappings, rather than having to provide a
configuration per board.
