This adds the QSPI2 controller to the SoC, and connects an SD
card to it. The generation of corresponding device tree source
fragment is also added.
Specify machine property `msel` to 11 to boot the same upstream
U-Boot SPL and payload image for the SiFive HiFive Unleashed board.
Note subsequent payload is stored in the SD card image.
