A user can use "--pm_notify_channel uart,allow_trigger_s5" to indicate
the User VM is allowed to trigger system S5.
"--pm_notify_channel uart" means a vuart channel will be created in the
User VM to allow communication with the VM's life_mngr. The Service VM
can then initiate S5 in the guest via its dm's monitor interface. The
additional option, "allow_trigger_s5", will create a socket connection
with the Service VM's life_mngr, allowing this VM to initiate system S5.
v1 -> v2:
- rename pm_notify_channel type to PWR_EVENT_NOTIFY_UART_TRIG_PLAT_S5

In addition to a single OVMF image (OVMF.fd), split images
(OVMF_CODE.fd, OVMF_VARS.fd) can be used to facilitate VM management.
From the OVMF Whitepaper:
The variable store and the firmware executable are also available in
the build output as separate files entitled: "OVMF_VARS.fd" and
"OVMF_CODE.fd". This enables central management and updates of the
firmware executable, while each virtual machine can retain its own
variable store.
An example to launch acrn-dm with the split images:
--ovmf code=/usr/share/acrn/bios/OVMF_CODE.fd, \
vars=/usr/share/acrn/bios/OVMF_VARS.fd
v1 -> v2:
- use memory-mapped file I/O for writeback
- use fcntl to lock OVMF image files

We could add MMIO device pass through by two ways:
a) If the MMIO device only has MMIO regions and no ACPI Table touched, using
"--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.
