Rename the tests to something more meaningful. I spent way too long
trying to get the test name right, failed, gave up and used a sequence
number instead. When I realized it wasn't because of the number of
underscores in the name that I really started to think. I didn't have
braces around the variable names ...

Thus: test_1 is now called apm_1x1_512_qcow, which gives you all you
need to run mkimg by hand.

Bump minimum linux compat version to support Centos6 ports updates for linux.

Update linux compat minimum revision to match linux-c6 now in ports.  This
is a candidate for 10.1 R as it matches the current state of supported

Correct display of bhyve SMBIOS UUIDs with dmidecode by bumping the version.

The mixed little/big-endianness of SMBIOS UUIDs was clarified in v2.6
of the SMBIOS spec. dmidecode uses the reported version of SMBIOS to
determine the layout and what to byte-swap.

bhyve's SMBIOS reported as 2.4 though it implemented the 2.6-style of
memory layout. This resulted in dmidecode reporting a different
UUID than one passed in via the -U option.

Fix by exporting a version of 2.6.

Move pci/ncr to dev/ncr.
Move amdsmb and nfsmb from dev/pci to their own device directory.
Move all the power management (SMBus) drivers to their own directory,
away from sys/pci.
Remove the empty sys/pci directory.
Remove "pci" from CSCOPEDIRS.
As per [1] Intel only supports this driver on 64bit platforms.
For now restrict it to amd64.  Other architectures might be
re-added later once tested.

Remove the drivers from the global NOTES and files files and move
them to the amd64 specifics.
Remove the drivers from the i386 modules build and only leave the
amd64 version.

Rather than depending on "inet" depend on "pci" and make sure that
ixl(4) and ixlv(4) can be compiled independently [2].  This also
allows the drivers to build properly on IPv4-only or IPv6-only
kernels.
