What's the reason for doing this?  I *think* it has something to do
with the fact that we currently have two "mtk_pcie_driver"
definitions: one in pcie-mediatek.c and the other in
pcie-mediatek-gen3.c, and apparently we want to make them different.

I can buy that.  But there are many other symbols with the same names
in the two drivers, e.g., mtk_pcie_probe(), mtk_pcie_remove().  Why is
mtk_pcie_driver special?

Maybe it's important that the of_device_id[] names be different?

This change is fine; I'd just like the commit log to have a little
more explanation of *why* it is useful.

Nit: I don't think this distinguishes the *controllers*.  It looks
like it distinguishes the *drivers*.
