asyncio is a new mechanism in ACRN, which is special for these devices
which need high IO performance. ACRN hypervisor would process the IO
request from User VM in an async mode.
Just like the original IOReq shared page, the devicemodel also create a
page for fastio requests. As the asyncio use the ioeventfd, so the
reuqests are handled in kernel, devicemodel only need to provide the
page.

Legacy VGA & VBE interface as a common interface is supported by
many legacy and modern OS. Many installer of OS distribution use
this interface to display the GUI of installer when setup a refresh
new installation on bare-metal. Besides, Windows OS always use this
interface to display it's BSOD, recovery mode & safe mode GUI. It
is need because Windows don't include virtio-gpu driver as their
in-box driver, VGA interface will be used before the virtio-gpu
driver been installed.
To be compatiable with the PCI bar layout of legacy VGA, the layout
is refined to meet with the requirement of legacy VGA and modern
virtio-gpu.

The UUID has several usages before:
1, For HV to identify the static VM configuration of post-launched VM.
2, Seed virtualization.
3, Slightly prevent launching malicous VM from SOS as lack of secure
boot.
The UUID is confused to user, user don't understand what it is. And user
don't know where to get/apply the UUID. The worst experience is user
can't launch any VMs w/o re-compile the hv. Everything needs to be
static decided in building phase.
Now we decide to remove UUID and split each usage. For 1st usage, use
vmname as the identifier of static VM configuration. For 2nd one, we
will use --vseed as the new parameter. For 3rd one, will pretect by
SOS's dm-verity.
This patch will remove the UUID parameter and support 1st&3rd usages
from DM part. For 2nd usage, another patch will be submitted later.

The current design has the following problem:

but ACRN-DM doesn't know this update.
ACRN-DM only know out-of-date gvt bar regions,
For simplicity, mark these bar regions as OOD bar regions.
uos kernel may allocate OOD bar regions for
other pci devices, which will result in ACRN-DM
bar regions inconsistency with uos kernel.
The new design is the following:
When other pci device update bar regions
(1) ACRN-DM updates gvt bars' regions
provided by a system file.
(2) ACRN-DM updates this pci device bar regions
v5 -> v6:
* add more comments
