Change 64-bit MMIO BAR window to 256G-512G
DM maps 64-bit mmio BARs of vdev into 4G-5G, for post-launched VMs. At native
platform, 64-bit MMIO BARs which have 39-bit address, are always mapped into
256G-512G address space.
DM will change the address window of 64-bit vdev BARs of post-launched VMs to
256G-512G. That ask OVMF to do the same change, to boot from passthrough SATA/MVME
disks, which have 64-bit MMIO BAR.

ACRN didn't support dynamic memory allocation. SO it would reserve
a big page pool and use the GPA as index to get a page to do EPT
mapping. In order to save memory, we put high MMIO windows to [4G, 5G].
AFter we support dynamic page allocation for EPT mapping, we move
high MMIO windows to where it used to ([256G, 512G]) for 39 bits physical
address), we could move high memory to where is used to too ([4G, 4G +
size]).

"--mmiodev_pt MMIO_regions",
b) If the MMIO device touches ACPI Table, using "--acpidev_pt HID"
Now only support TPM2 MSFT0101 MMIO device pass through through launch script
using "--acpidev_pt MSFT0101". When we want to pass through the TPM2 deivce,
we would not allow to emulate the vTPM2 at the same time. This is becuase
the ACRN-DM emulate the TPM2 as MSFT0101 too. Otherwise, the VM can't boot.
Besides, we could only support one TPM2 device PT and one MMIO device PT.
For TPM2 device PT, the MMIO resources are hard-coded. For the MMIO device PT,
we could pass through the MMIO resources on the cmdline.
ToDo:
1. We may use HID to discover the MMIO regions and ACPI Table instaed of
hard-coded.
2. To identify a MMIO device only by MMIO regions.
3. To allocate virtual MMIO regions in a reserved guest MMIO regions.

Some passthrough devices have no reset mechanisms which cause the device stay
in unknown status during boot/reboot flow. And such unknown status cause
unexpected behaviors in the guest. Except the ordinary reset mechanisms
like FLR, we can utilize enter/exit D3cold as the reset that D3cold will
power gate the entire hardware. But the D3cold is implemented as ACPI
method which has no user interface in the SOS side. But the D3cold is
implemented as ACPI method which has no user interface in the SOS side.
But base on our experience, some devices can utilize D3hot instead of
D3cold. But it is not useful for all PCI devices as the power status
of D3hot is implementation defined.
Provide one new API to program PowerState(D0/D1/D2/D3hot) in PMCSR
register.
Add "d3hot_reset" sub-parameter for passthrough device to enable utilize
enter/exit D3hot flow to implement reset mechanisms.

There has one bug that the pci_xhci_dev_emu objects recorded in
xdev->devices haven't destroy when OVMF transfer to guest OS.
This will cause the the fds of usbfs can't be freed in libusb.
The OVMF xHCI driver needs to disable all enabled slots during
graceful existing flow, but it doesn't.
The USBCMD.HCRST bit is used for xHC reset that will be triggered
in xHCI driver initialization. We can use this chance to clear
all pci_xhci_dev_emu objects

OpRegion: 8KB(0x2000)
[ OpRegion Header ] Offset: 0x0
[ Mailbox #1: ACPI ] Offset: 0x100
[ Mailbox #2: SWSCI ] Offset: 0x200
[ Mailbox #3: ASLE ] Offset: 0x300

[ Mailbox #5: ASLE EXT ] Offset: 0x1C00
Extended OpRegion: 8KB(0x2000)
[ Raw VBT ] Offset: 0x0
Generally VBT stores in MailBox4 in OpRegion which max size is 6KB.
If VBT larger than 6KB, it will be stored in extended OpRegion which
is neighborhood with legacy OpRegion. In this case, we need to
passthrough extended OpRegion also to support GVT-d feature. The
OpRegion size that we passthrough should be (OpRegion+Extended)=16KB
ASLE.rvda stores the location of VBT.
For OpRegion 2.1+: ASLE.rvda = offset to OpRegion base address
For OpRegion 2.0: ASLE.rvda = physical address
To-do: Add support for OpRegion on some platforms(eg. APL)

2. Add support for macvtap interface.
3. Identify macvtap vs tap interface and

Some OSes assume the platform must have the IOAPIC. For example:
Linux Kernel allocates IRQ force from GSI (0 if there's no PIC and IOAPIC) on x86.
And it thinks IRQ 0 is an architecture special IRQ, not for device driver. As a
result, the device driver may goes wrong if the allocated IRQ is 0 for RTVM.
This patch expose vIOAPIC to RTVM with LAPIC passthru even though the RTVM can't
use IOAPIC, it servers as a place holder to fullfil the guest assumption.
After vIOAPIC has exposed to guest unconditionally, the 'ready' field could be
removed since we do vIOAPIC initialization for each guest.

It causes one issue that if one of the two VMs is rebooting/shutdown,
