8dc07838db hyperv/vmbus: Add tunable to pin/unpin event tasks.
Event tasks are pinned to their respective CPU by default, in the same
fashion as they were.

Unpin the event tasks by setting hw.vmbus.pin_evttask to 0, if certain
CPUs serve special purpose.

554e6778b6 hyperv/vmbus: Reorganize vmbus device tree
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@.

cdb316ee87 hyperv/vmbus,pcib: unbreak build in case NEW_PCIB is undefined
vmbus_pcib requires NEW_PCIB, but in case that's not defined, we at
least shouldn't break build.

c8b32f717d hyperv/vmbus: add a new method to get vcpu_id
vcpu_id is host's representation of guest CPU.
We get the mapping between vcpu_id and FreeBSD kernel's cpu id when VMBus
driver is loaded. Later, when a driver, like the coming pcib driver, talks
to the host and needs to refer to a guest CPU, the driver must use the
vcpu_id.
