Keep the old add_spi_flash call commented for now just in case we need to compare/test it.

1bitsquared_icebreaker: Add test code to use LiteSPI.
Both XiP from SPI(1X) or QSPI(4X) are working, but resource usage is currently
too high to be able to switch to it by default. We'll first try to reduce it.
