Can we first split the kstrotox* (and simple_strto*) to the separate
header first?

On top of that, why kstrtodev_t is so important? How many users are
already in the kernel to get an advantage out of it?
What to do with all other possible variants ("%d:%d", "%dx%d" and its
%u variant, etc)?

Why simple_strto*() can't be used?

Perhaps preserve order? (It's for the future, since I doubt we will
get this in upstream anyway).
