PNP info has the unfortunate requirement that it must follow the
associated module definition in the module metadata linker set.
Otherwise devmatch can segfault while processing the linker hints file
since kldxref maintains the order in the linker set.
I found a number of drivers that violate this requirement after
debugging a devmatch crash on a 32-bit ARM system. We really need a
better solution than this, but let's try to work around the problem for
13.0 at least.
