arm: mvebu: turris_mox: add support for board rescue mode
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
