Li Fei1 e99ddf28c3 hv: vpci: handle the quirk part for pass through pci device cfg access in dm 
There're some PCI devices need special handler for vendor-specical feature or
capability CFG access. The Intel GPU is one of them. In order to keep the ACRN-HV
clean, we want to throw the qurik part of PCI CFG asccess to DM to handle.

To achieve this, we implement per-device policy base on whether it needs quirk handler
for a VM: each device could configure as "quirk pass through device" or not. For a
"quirk pass through device", we will handle the general part in HV and the quirk part
in DM. For a non "quirk pass through device",  we will handle all the part in HV.

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
