HV: deny HV owned PCI bar access from SOS

Browse Source 
This patch denies Service VM the access permission to device resources
owned by hypervisor.
HV may own these devices: (1) debug uart pci device for debug version
(2) type 1 pci device if have pre-launched VMs.
Current implementation exposes the mmio/pio resource of HV owned devices
to SOS, should remove them from SOS.
