qemu and nvmm

[Robert Nestor <rnestor%mac.com@localhost>]

Now that nvmm is a part of the NetBSD 9.0 upcoming release, doesn’t it make sense to pull qemu-nvmm up from wip?  Either replacing qemu with qemu-nvmm or pulling qemu-nvmm in as a new package would work and eliminate the need for users having to set up pkgsrc builds, pull in wip  and built it for themselves just to work with nvmm. That would certainly make it easier for people to play with nvmm.
