fix EPT cache attributes

Description of patch:

hardcode UC for mmio of assigned devices in ept table similarly to what was
done for p2m.

Upstream Status: Accepted (in a different form)
This patch differs from upstram since it is a simplification, upstream
uses a more invasive change to allow finer grain control through the
MTRR/PAT registers, more flexible but not needed for the current use
cases for VTd.

Process error, don't need a separate BZ per patch
