This patch prepares vRTCT for post-RTVM instead of

- Configurations are based on Service VM native RTCT.
- Remap vLAPIC IDs in vRTCT.
- Remap base address of SW SRAM memory regions
from HPA to GPA.
- HPA base of Software SRAM shall be parsed from PTCT
instead of hardcoding.

dm: vptct: add vPTCT for post-launched RTVM
We added vPTCT support for post-launched RTVM:
1. Added a function create_and_inject_vptct. Currently, we
pass-through the whole pSRAM to one RTVM, so we will also pass-
through the PTCT to the very same RTVM. This function will
read the native PTCT from SOS and inject it into post-
launched VM's vACPI.
2. Added some definitions for vPTCT.

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.

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.

entry -> pthread_cond_wait() -> spurious wakeup ->
vq_clear_used_ring_flags() -> segfault (vq->used uninitialized)
tpm_crb_request_deliver():
entry -> pthread_cond_wait() -> spurious wakeup ->
swtpm_handle_request() called needlessly
virtio_rnd_get_entropy():
entry -> pthread_cond_wait() -> spurious wakeup ->
no avail ring processing ->
virtio_rnd_notify() skips pthread_cond_signal() due to

vq_endchains() called needlessly ->
wait in pthread_cond_wait() indefinitely
Fix these uses of pthread_cond_wait() by using predicates.

trb prior to Stop Endpoint Command complete event trb. It should be a
big change and for short term, do nothing for the stop endpoint command
which is no other side effect be observed so far.

NHLT table contains the settings some audio drivers need.
An ACPI method is used to get NHLT table address & length.
In current DM code, the NHLT talbe length in the ACPI method
is hardcoded, which will cause troubles when the length of the
table changed.
This patch replaces the hardcoded NHLT table length according to
the table length read from SOS.
