hv: Remove multiple definitions for dmar translation structures

Browse Source 
Except for few translation structures in x86 IOMMU, all translation
structures are 128-bit. All the translation structures used by ACRN
are 128 bit. So removed multiple definitions and defined a struct
that accomodates 128 bit entries.
