Prepare `kwboot` for the initial system installation

Ensure that the jumpers are set to `0 1 0 0 1` (default for eMMC boot is `0 0 1 1 1`), and then use U-Boot's `kwboot` tool:
```sh
-./tools/kwboot -b ./u-boot-spl.kwb -t -p /dev/ttyUSB0
+./host/bin/kwboot -b ./u-boot-spl.kwb -t -p /dev/ttyUSB0
```
Once in U-Boot (a stock factory image is OK as well), plug a USB flash disk which contains `images/usb-flash.img` and execute:
