Add necessary config options and board code to support board factory
reset / rescue mode on Turris MOX.

In order to also support invoking rescue mode from U-Boot console,
without having to press the factory reset button, put the rescue command
into `bootcmd_rescue` default environment variable. When factory reset
button is pressed, invoke rescue mode via distroboot by setting
`boot_targets` to `rescue`.

Rescue boot from console can be invoked by running
  run bootcmd_rescue

Make it possible to invoke rescue boot from U-Boot console, without
having to press the factory reset button. This is needed when accessing
the device remotely, for example.

Achieve this by putting rescue command into `bootcmd_rescue` default
environment variable and setting some distroboot environment variables
to their default values when the factory button is pressed.

Rescue boot from console can be invoked by running
  run bootcmd_rescue
