Work on the new the SPI interface

Transfers over the SPI1 channel of the SAME70 working
Refactored GCodeBuffer for two data types:
1. For string-based inputs (standard text-based approach)
2. For binary data transfers as used in the new SPI protocol (untested)
Added OpenOCD script for SAME70 <-> Atmel ICE
Fixed relative workspace paths in the linker settings again
