Add SPI clock divider support for 120MHz SAMD boards. #54

Hello!

I ran into an issue with the BME280 library on the SAMD51 Thing Plus; I think this is the appropriate fix and will likely fix other SPI-related bugs in other libraries.

Another option would be to define the SPI clock dividers e.g.

  #define SPI_CLOCK_DIV2  ((F_CPU / 16000000) * 2)

to support faster boards in the future.

Cheers!

added support in SAMD boards v1.7.1. Thanks for the PR!
