If enabled, SPI 0 is reserved for accessing the SPI flash ROM and a
driver interface won't be instantiated for SPI 0.
Beware disabling this option on HiFive 1! The SPI flash ROM is where the
program is stored, and if this driver initializes the interface for
peripheral control the FE310 will crash on boot.
