The HiFive Unleashed and HiFive Unmatched boards do not enable the
SPI0 controller that the flash is connected to. This test will not
build on these platforms because SPI0 bus controller is missing.

By default the hifive1 board doesn't enable the SPI controller that
the flash is on. As such this test will not build on that platform
due to lack of a missing SPI bus controller device.
