Now, we have assumption that SOS control whether the platform
should enter S5 or not. So when SOS tries enter S5, we just
forward the S5 request to native port which make sure platform
S5 is totally aligned with SOS S5.
With higher serverity guest introduced,this assumption is not
true any more. We need to extend the platform S5 process to
handle higher severity guest:
- For DM launched RTVM, we need to make sure these guests
is off before put the whole platfrom to S5.
- For pre-launched VM, there are two cases:
* if os running in it support S5, we wait for guests off.
* if os running in it doesn't support S5, we expect it
will invoke one hypercall to notify HV to shutdown it.
NOTE: this case is not supported yet. Will add it in the
future.

1. for post-launch general VM, like LaaG, the vUART is emulated in DM,
so the power off control channel is:
acrn-dm:pty[master <-> salve] <--> acrn-dm:vUART <--> UOS:vUART
2. for RTVM, like RT-Linux, the vUART is emulated in hypervisor layer,
so the control channel is:
acrn-dm <--> SOS:/dev/ttyS1 <--> Hypervisor <--> UOS:vUART.
So the settings in launch script are different.

We did following to do platform reset:
1. Try ACPI reset first if it's available
2. Then try 0xcf9 reset method
3. if 2 fails, try keyboard reset method
This introduces some timing concern which needs be handled carefully.
We change it by following:
assume the platforms which ACRN could be run on must support either
ACPI reset or 0xcf9 reset. And simplify platform reset operation
a little bit:
If ACPI reset register is generated
try ACPI reset
else
try 0xcf9 reset method

Fix tsc_deadline issue by trapping TSC_DEADLINE msr write if VMX_TSC_OFFSET is not 0.
Because there is an assupmtion in the ACRN vART design that pTSC_Adjust and vTSC_Adjust are
both 0.
We can leave the TSC_DEADLINE write pass-through without correctness issue becuase there is
no offset between the pTSC and vTSC, and there is no write to vTSC or vTSC_Adjust write observed
in the RTOS so far.
This commit fix the potential correctness issue, but the RT performance will be badly affected
if vTSC or vTSC_Adjust was not zero, which we will address if such case happened.
