I have severals layers in my boot chain, and I want to use bootcount
in severals layers to manage boot issues. If severals layers use the
same variable name (bootcount) and a boot issue happen, I can't find
the layer that fails.
So I propose to "customize" the bootcount variable name.

As it is "unique", I can't chain severals bootcount.
That's why I propose an option to customize the bootcount name variable.
I know that it's a "corner case" and that you could prefer to avoid
adding another option, that's why I've proposed this option as a RFC.
