hyperv/pcib: change the file name: pcib.c -> vmbus_pcib.c
This makes the file name and the variable naming in the file consistent.

hyperv/pcib: Fix the build for some kernel configs
Add the dependency on pci explicitly for the pcib and vmbus drivers.
The related Makefiles are updated accordingly too.

hyperv/pcib: enable PCIe pass-through (a.k.a. Discrete Device Assignment)
The feature enables us to pass through physical PCIe devices to FreeBSD VM
running on Hyper-V (Windows Server 2016) to get near-native performance with
low CPU utilization.
The patch implements a PCI bridge driver to support the feature:
1) The pcib driver talks to the host to discover device(s) and presents
the device(s) to FreeBSD's pci driver via PCI configuration space (note:
to access the configuration space, we don't use the standard I/O port
0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V,
which is very similar to the 0xCF8/CFC method).
2) The pcib driver allocates resources for the device(s) and initialize
the related BARs, when the device driver's attach method is invoked;
3) The pcib driver talks to the host to create MSI/MSI-X interrupt
remapping between the guest and the host;
4) The pcib driver supports device hot add/remove.
