[U-Boot] [RFC] cmd: add bootslot command to select/boot slot based on boot counts

Dear Martin,

This is not a correct summary of the current implementation.  If
the boot count exceeds the limit, some _alternative_boot_command_ is
executed.

The trivial case is to boot another image / partion or such.

Butt nothing prevents you to run any more sophisticated scripts
here.

This can easily implemented with a few lines of shell code as well.

I think it makes no sense to add a lot of code that can be
implemented as a few lines of shell scripts as well, especially as
this code is neither time critical nor has the potential of becoming
widely used.
