qemu-*: Show how to enable restricted/basic in board config
For iterating, enabling these in the board config is easiest.  It's
also possible to manually inject config.user ahead of time, or enable
at runtime without flashing, but the normal enable/flash/reboot path
does not work in qemu since it is unable to flash.
