This change reverts stable/10@r282122 and stable/10@r288340, and re-MFCs the
series again (r282122, r285339, and r288340).

More changes are pending to nv(9)/pci(4) after further review/work. Please see
the Phabricator review for more details (both https://reviews.freebsd.org/D4232
and https://reviews.freebsd.org/D4249 ).

- Tested with:
-- Booting VMware Fusion 8.1.0 running on a Haswell Apple Macbook Pro
-- Booting a Haswell machine with zfs and running some stress workloads with
   VirtualBox guests
-- make tinderbox
-- kyua test -k /usr/tests/lib/libnv
