The current code declare pci_bar structure following the PCI bar spec. However,
we could not tell whether the value in virtual BAR configuration space is valid

Issue description:
-----------------
Machine Check Error on Page Size Change
Instruction fetch may cause machine check error if page size
and memory type was changed without invalidation on some
processors[1][2]. Malicious guest kernel could trigger this issue.
This issue applies to both primary page table and extended page
tables (EPT), however the primary page table is controlled by
hypervisor only. This patch mitigates the situation in EPT.
Mitigation details:
------------------
Implement non-execute huge pages in EPT.
This patch series clears the execute permission (bit 2) in the
EPT entries for large pages. When EPT violation is triggered by
guest instruction fetch, hypervisor converts the large page to
smaller 4 KB pages and restore the execute permission, and then
re-execute the guest instruction.
The current patch turns on the mitigation by default.
The follow-up patches will conditionally turn on/off the feature
per processor model.

We now have four methods to configure board and scenario when
build acrn (sorted with priority):
1. Change them with "make menuconfig" in hypervisor directory
2. Give baord_file/scenario_file as make command parameters
3. Give BOARD/SCENARIO as make command parameters
4. Use BOARD/SCENARIO default value defined in Makefile file
With this patch, we make sure we follow priority exactly.

For vuart1, if it's mapped to a real native serial port, we must
re-use the native serial port io base and irq number. If no native
serial port is mapped to vuart1, non-exist io base and irq should
be used.
Please note: UOS launch script may need be updated according to
which serial port index is used by vuart1.
Now, we are using ttyS1 of SOS for vuart1 in our release. User may
need to remap vuart to different ttySx by following above rule if
ttyS1 in user platform is used by other devices like Bluetooth/Wifi.
