vmd(4): Major driver refactoring

- Re-implement pcib interface to use standard pci bus driver on top of
vmd(4) instead of custom one.
- Re-implement memory/bus resource allocation to properly handle even
complicated configurations.
- Re-implement interrupt handling to evenly distribute children's MSI/
MSI-X interrupts between available vmd(4) MSI-X vectors and setup them
to be handled by standard OS mechanisms with minimal overhead, except
sharing when unavoidable.

Successfully tested on Dell XPS 13 laptop with Core i7-1185G7 CPU (VMD
device ID 0x9a0b) and single NVMe SSD, dual-booting with Windows 10.

Successfully tested on Supermicro X11DPI-NT motherboard with Xeon(R)
Gold 6242R CPUs (VMD device ID 0x201d), simultaneously handling NVMe
SSD on one PCIe port and PLX bridge with 3 NVMe and 1 AHCI SSDs on
another. Handles SSD hot-plug (except Optane 905p for some reason,
which are not detected until manual bus rescan) and enabled IOMMU
(directly connected SSDs work, but ones connected to the PLX fail
without errors from IOMMU).

xen/timer: fix amd64 LINT kernel build

On amd64 XENHVM depends on the xentimer device for PVH early startup,
so both should be added or removed together (like the current
dependency with xenpci). Fix this by adding xentimer to NOTES and
updating the comments on the config files. Note that on i386 there's
no such dependency between xentimer and XENHVM, since there's no PVH
support.

While there also fix the MINIMAL i386 build to include the xentimer,
so it keeps the same functionality as before xentimer was split from
XENHVM.

Use envvar rather than nonstandard hint. lines

The NOTES files have a bunch of hint lines that are removed when
generating LINT. However, we can achieve the same effect by prepending
each of the lines with 'envvar' so the NOTES files become standard
config(8) files. No functional changes as the sed script to generate
the LINT files filters these either way.

ice(4): Introduce new driver for Intel E800 Ethernet controllers

The ice(4) driver is the driver for the Intel E8xx series Ethernet
controllers; currently with codenames Columbiaville and
Columbia Park.

These new controllers support 100G speeds, as well as introducing
more queues, better virtualization support, and more offload
capabilities. Future work will enable virtual functions (like
in ixl(4)) and the other functionality outlined above.

For full functionality, the kernel should be compiled with
"device ice_ddp" like in the amd64 NOTES file, and/or
ice_ddp_load="YES" should be added to /boot/loader.conf so that
the DDP package file included in this commit can be downloaded
to the adapter. Otherwise, the adapter will fall back to a single
queue mode with limited functionality.

A man page for this driver will be forthcoming.

[aacraid] Port driver to big-endian

Port aacraid driver to big-endian (BE) hosts.

The immediate goal of this change is to make it possible to use the
aacraid driver on PowerPC64 machines that have Adaptec Series 8 SAS
controllers.

Adapters supported by this driver expect FIB contents in little-endian
(LE) byte order. All FIBs have a fixed header part as well as a data
part that depends on the command being issued to the controller.

In this way, on BE hosts, the FIB header and all FIB data structures
used in aacraid.c and aacraid_cam.c need to be converted to LE before
being sent to the adapter and converted to BE when coming from it.

The functions to convert each struct are on aacraid_endian.c.
For little-endian (LE) targets, they are macros that expand
to nothing.
In some cases, when only a few fields of a large structure are used,
the fields are converted inline, by the code using them.
