hv: deny the launch of VM if pass-thru PIO bar isn't identical mapping

Browse Source 
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

Tracked-On: #6508
