In the virtualized environment, forcewake operations are not
necessory for the driver, because mmio accesses will be trapped
and emulated by the host side, and real forcewake operations are
also done in the host. New mmio write handlers are added to directly
call the __raw_i915_write, therefore will reduce many traps and
increase the overall performance for drivers runing in the VM
with Intel GVT-g enhancement
Explain why this is not done inside uncore_init.

Hi Chris,
The gpu_active flag is set by intel_detect_vgpu(), which uses I915_READxx, should be after intel_uncore_init.
