There was some secure coding style violations of virtio net and tmp,
this patch add some NULL check to fix these violations.

Many of the license and Intel copyright headers include the "All rights

throughout the code (hypervisor, devicemodel and misc).

This patch enables TPM2 passthrough to post-launched VM with eventlog
support.
User starts by providing command line "--acpidev_pt <TPM2_HID>",
of which the <TPM2_HID> will be searched from /proc/iomem for TPM2 buffer
start address and size. Furthermore, If TPM2 eventlog is supported,
TPM2 eventlog information will be retrieved from sysfs TPM2 table and
passed-through as well.
v4 -> v5:
move tpm2 related logic from acpi.c to tpm.c
multiple API rename

This patch refines the ACPI device passthrough framework by defining a
generic framework. Note that when user gives an HID by "--acpidev_pt
<HID>", the pt logic will go through all registered ops to see if
there's a match.
v4 -> v5:
parse_pt_acpidev/parse_pt_mmiodev -> create_pt_acpidev/create_pt_mmiodev
(there were already "init_xxx" function present, so rename to
create_xxx)
"super user" -> "superuser"
multiple API renames

The ACPI MMIO devices, like TPM, has a fixed base GPA. Sould support
GPA resource allocating for MMIO devices. GPA region
0xF0000000~0xFE000000 is not used, can allocate GPA from it.

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.
