clearfog: Add a crude eMMC flashing script

Boot the board via UART with a USB flash disk loaded with
`usb-flash.img`:

  ./tools/kwboot -b ./u-boot-spl.kwb -t -p /dev/ttyUSB0
  usb start; fatload usb 0:1 00800000 boot.scr; source 00800000

Run this from within U-Boot:

  mount /dev/sda1 /mnt; sh /mnt/usb-reflash-factory.sh

Don't forget to re-jumper the board for eMMC boot afterwards (00111), do
not leave it in the UART mode (01001).
