drm/i915/gvt: Revert "drm/i915/gvt: Refine the snapshort range of I915 MCHBAR to optimize gvt-g boot time"
This reverts commit
2dd4b3d721837f063d90798a241c5a8b6267b162.
BXT needs to access 0x141000-0x1417ff register to obtain the dram info.
But after the snapshot range of I915_MCHBAR is refined in
2dd4b3d721,
it only initializes the range of 0x144000-0x147fff for VGPU and then
causes that the guest GPU can't get the initialized value for dram
detection on BXT.
