vtd: Enable pass-through translation for Dom0

If pass-through field in extended capability register is set, set
pass-through translation type for Dom0, that means DMA requests with
Untranslated addresses are processed as pass-through in Dom0, needn't
translate DMA requests through a multi-level page-table.
