hv: vtd: use EPT as translation table for PTDev in SOS

Browse Source 
In current code, the address translation type for passthrough devices
in SOS is passthrough type, which means the device in SOS can access
the whole physcial memory.
This patch uses SOS EPT to translate address for passthrough
devices. So that the memory of VMM or trusty can be protected from
SOS PTDev.
