[PATCH] config/sifive_unmatched: add preboot commands

[Alexander von Gluck IV]

* Opens up u-boot to properly search through USB media
  for a valid boot media
* The MMC on the unmatched is slow, so a model of running
  the OS from USB or NVMe is a compelling one. (putting just
  u-boot on the sd card)
