When using the standard, unmodified Arduino libraries for ESP32, the SPI library
uses a default set of pins for SPI that are not the same that this board uses.
We thus configure SPI as soon as possible - the library will then "remember" these
settings later on (especially in LMIC - LoRaWan where it is used)
