Jian Jun Chen 2acbebf6dc dm/VBS-U: implement virtio_set_modern_bar 
virtio_set_modern_bar is an external interface that backend virtio
driver can call to initialize the PCI capabilities and PCI bars
defined in the virtio 1.0 spec.

The following are done in the function:

- 5 PCI capabilities are added to the PCI configuration space of the
  virtio PCI device. (common/isr/device_specific/notify/cfg_access)

- A 64-bit MMIO bar is allocated to accommodate the registers defined
  in the 4 PCI capabilities. (cfg_access capability does not require
  MMIO.)

- If use_notify_pio is true, a PIO notify capability is added to the
  PCI configuration space and a PIO bar is allocated for it
  accordingly.

ACRN Device Model
#################

Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the Service OS and Guest OSs. It is a component that is used in conjunction with the `ACRN Hypervisor`_ and this is installed within the Service OS. You can find out more about Project ACRN on the `Project ACRN documentation`_ website.
