tboot patch 5/5 - use protected DMAR

The VT-d DMAR ACPI tables may not be DMA protected by tboot.
However, SINIT saves a copy of them in the SinitMleData struct
in the TXT heap (which is DMA protected). So we should read
the DMAR table from that copy if launched by tboot.

tboot patch 4/5 Hypervisor S3 integrity

tboot patch 3/5 - protect TXT ranges

tboot no longer marks the TXT heap/SINIT/private config space
as E820_UNUSABLE in the e820 table, so Xen must mark them so
(to disallow them from dom0).
