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.
