The most important things for patch splitting are:
 * everything still has to compile cleanly
 * the contents of a single patch should be a coherent single
   thing that it makes sense to review in one part

If there's something in there that only touches 20 lines of
code but is a coherent single change, it's fine to have that in
its own patch -- small patches are easy to review.

At the upper end, I tend to think a patch is a bit big
at around 200 lines, but for the specific case of "here
is a new device" bigger than that is OK, because it's
just adding new files rather than merging changes into
existing ones.

https://www.qemu.org/docs/master/devel/submitting-a-patch.html
has some other advice on patch submission, if you haven't
read that yet.
