Subject: [PATCH char-misc-next 0/8] Enable Virtio Over PCIe (VOP) driver

This patch series moves virtio functionality from the MIC host/card
driver into a separate hardware independent Virtio Over PCIe (VOP)
driver. Apart from being moved into a separate driver the functionality
is essentially unchanged. This refactoring allows this hardware
independent logic to be shared easily across multiple generations of
MIC devices. The original commits are listed below for reference:
- commit f69bcbf3b4c4 ("Intel MIC Host Driver Changes for Virtio Devices.")
in drivers/misc/mic/host/mic_virtio.c
- commit 2141c7c5ee67 ("Intel MIC Card Driver Changes for Virtio Devices.")
in drivers/misc/mic/card/mic_virtio.c

The patch series is partitioned as follows:
1) Removes MIC X100 host virtio functionality
2) Removes MIC X100 card virtio functionality
3) Enables the Virtio Over PCIe (VOP) bus which abstracts the
   low level hardware details like interrupts and mapping remote
   memory so that the same VOP driver can work without changes
   with different MIC host or card drivers as long as the hardware
   bus operations are implemented.
4) Adds data structures for the VOP driver
5) Enables VOP host side functionality
6) Enables VOP card side functionality
7) Enables VOP debugfs and driver build
8) Implements the MIC host and card driver changes to enable VOP
