This patch removes the MIC drivers from the kernel tree
since the corresponding devices have been discontinued.
Removing the dma and char-misc changes in one patch and
merging via the char-misc tree is best to avoid any
potential build breakage.

Since card side COSM functionality, to trigger MIC device shutdowns
and communicate shutdown status to the host, is now moved into a
separate COSM client driver, this patch removes this functionality
from the base MIC card driver. The mic_bus driver is also updated to
use the device index provided by COSM rather than maintain its own
device index.

This patch introduces the host "Virtio over PCIe" interface for
Intel MIC. It allows creating user space backends on the host and instantiating
virtio devices for them on the Intel MIC card. It uses the existing VRINGH
infrastructure in the kernel to access virtio rings from the host. A character
device per MIC is exposed with IOCTL, mmap and poll callbacks. This allows the
user space backend to:
(a) add/remove a virtio device via a device page.
(b) map (R/O) virtio rings and device page to user space.
(c) poll for availability of data.
(d) copy a descriptor or entire descriptor chain to/from the card.
(e) modify virtio configuration.
(f) handle virtio device reset.
The buffers are copied over using CPU copies for this initial patch
and host initiated MIC DMA support is planned for future patches.
The avail and desc virtio rings are in host memory and the used ring
is in card memory to maximize writes across PCIe for performance.

This patch enables the following features:
a) Boots and shuts down the card via sysfs entries.
b) Allocates and maps a device page for communication with the
card driver and updates the device page address via scratchpad
registers.
c) Provides sysfs entries for shutdown status, kernel command line,
ramdisk and log buffer information.
