Removed Wire and SAMD_AnalogCorrection libraries from HW section, as we didn't change anything in those, so let's keep it to the standard ones Modified SPI library, initializing extra SPI ports, also HW mux changes in the setup of individual SPI ports to match the GW setup Added MyHWSAMD files so they are included in the core headers (MyConfig.h / MySensors.h)
