In current design, when pass-thru dev,
for the PIO bar, need to ensure the guest PIO start address
equals to host PIO start address.
But malicious guest may reprogram the PIO bar,
then hv will pass-thru the reprogramed PIO address to guest.
This isn't safe behavior.
When guest tries to reprogram pass-thru dev PIO bar,
inject #GP to guest directly.

In current design, when pass-thru dev,
for the PIO bar, need to ensure the guest PIO start address
equals to host PIO start address.
Then set the VMCS io bitmap to pass-thru the corresponding
port io to guest for performance.
ACRN-DM and acrn-config should ensure the identical mapping of PIO bar.
If ACRN-DM or acrn-config failed to achieve this,
we should deny the launch of VM

In the commit of 4e1deab3d9, we changed the
init sequence that init paging first and then init e820 because we worried
about the efi memory map could be beyond 4GB space on some platform.
After we double checked multiboot2 spec, when system boot from multiboot2
protocol, the efi memory map info will be embedded in multiboot info so it
is guaranteed that the efi memory map must be under 4GB space. Consider that
the page table will be allocated in free memory space in future, we have
to change the init sequence back that init e820 first and then init paging.
If we need to support other boot protocol in future that the efi memory map
might be put beyond 4GB, we could have below options:
1. Request bootloader put efi memory map below 4GB;
2. Call EFI_BOOT_SERVICES.GetMemoryMap() before ExitBootServices();
3. Enable a early 64bit page table to get the efi memory map only;

This patch changes the size of vvmcs[] array from 1 to
PER_VCPU_ACTIVE_VVMCS_NUM, and actually enables multiple active VMCS12
support in ACRN. The basic operations:
- if L1 VMPTRLDs a VMCS12 without previously VMCLEAR the current
VMCS12, ACRN no longer unconditionally flushes the current VMCS12
back to L1. Instead, it tries to keep both the current and the newly
loaded VMCS12 in the nested->vvmcs[] array, unless:
- if there is no more available vvmcs[] entry, ACRN flushes one active
VMCS12 to make room for this new VMCS12.

The default value population algorithm introduced by commit
2bfaa34 ("config_tools: populate default values in scenario XML") only
populates default values to the first occurrence of a tag when the tag is
specified to allow multiple occurrences under an xs:all node. This may lead
to incomplete scenario XML as some of the default values are missed.
This patch fixes this issue by checking **all** nodes having the same tag
under a node specified by an xs:all schema.
