uos IGD driver need opregion when enable GVT-d.
This patch pass-thru opregion to uos gpu.
Here is the steps:
(1) set opregion gpa(guest physical addrress) 0xDFFFD000;
(2) get opregion hpa(host physical addrress);
(3) build EPT mapping for opregion.
v1 -> v2:
* initialize the EPT mapping for passthrough GPU opregion region
in passthru_init instead of reading the ASLS config space
v2 -> v3:
* add EPT unmap when deinit
* change some micro name
