Colin Xu 6da5756200 drm/i915/gvt: Init DPLL/DDI vreg for virtual display instead of inheritance. ... commit f965b68188ab59a40a421ced1b05a2fea638465c upstream. Init value of some display vregs rea inherited from host pregs. When host display in different status, i.e. all monitors unpluged, different display configurations, etc., GVT virtual display setup don't consistent thus may lead to guest driver consider display goes malfunctional. The added init vreg values are based on PRMs and fixed by calcuation from current configuration (only PIPE_A) and the virtual EDID.
