Set default SPI flash access mode to DIO We have a bunch of boards out there (the NodeMCU-lookalike, breadboardable boards) in the hands of early reviewers. Because the flash chips on these boards have a different command to go into QIO mode, ESP-IDF will break on these boards out of the box. Eventually, we need some nifty way to autodetect this or something, but for now, the quick fix is to make DIO the default access mode. Once this is merged, I will also modify the default in the template apps sdkconfig. See merge request !65
