hv: vm: enable iommu after vpci init

Browse Source 
In current code, vpci do the pci enumartion and add pci devices to the
context table of iommu.
Need to enable iommu DMA address translation later than vpci init.
Otherwise, in UEFI platform, there will be a shot time that address translation
is enabled, but the context table is not setup.
For the devices active in UEFI environment will have problem on address translation.
