For GEN1 Hyper-V, vmbus is attached to pcib0, which contains the
resources for PCI passthrough and SR-IOV. There is no
acpi_syscontainer0 on GEN1 Hyper-V.
For GEN2 Hyper-V, vmbus is attached to acpi_syscontainer0, which
contains the resources for PCI passthrough and SR-IOV. There is
no pcib0 on GEN2 Hyper-V.
The ACPI VMBUS device now only holds its _CRS, which is empty as
of this commit; its existence is mainly for upward compatibility.
Device tree structure is suggested by jhb@.

be pulled into FreeBSD. From now, FreeBSD will be considered the
upstream repo.
First step: move the drivers away from the contrib area and into
the base system.
A follow-on commit will include the drivers in the amd64 GENERIC kernel.
