Add auto-boot timeout for U-Boot's bootflow menu

Otherwise, you have to press enter to boot your distro.

With this, a timeout is created. After a number of seconds,
which can be reconfigured, the first option selected will be booted,
when generating a bootflow menu.

The timeout is disabled when you navigate the menu; it only
kicks in if you don't input anything on the keyboard.

More information about how this works is in the U-Boot patches,
within this patch. I've set the timeout to 8 seconds.

-
-Otherwise, you have to press enter to load from a boot option,
-which is unacceptable on headless setups.
-
-If you press the arrow keys to interrupt it, the timer will stop
-and you must then press enter to boot an option.
-
-Otherwise, if you just leave U-Boot to do its thing, it will
-automatically boot what was selected, e.g. installed OS.
