The board is compatible with Arduino UNO and Arduino MEGA shields and has an ISP connector, so this adds the corresponding features. This adds the Arduino I/O-mapping for the ISP SPI and provides the corresponding feature. It appears that the SPI on D11/D12/D13 cannot be provided by a SERCOM, this is under clarification at [1]. For now, no I/O mapping for that SPI bus is provided. [1]: https://forums.adafruit.com/viewtopic.php?t=214093

Contribution description
The board is compatible with Arduino UNO and Arduino MEGA shields and has an ISP connector, so this adds the corresponding features.
This adds the Arduino I/O-mapping for the ISP SPI and provides the corresponding feature.
It appears that the SPI on D11/D12/D13 cannot be provided by a SERCOM, this is under clarification at 1. For now, no I/O mapping for that SPI bus is provided.
Testing procedure
An Arduino Shield that uses the ISP SPI bus (the older ones targeting the AVR based Arduinos still do that) should now work out of the box.
