Need a explicit write_vreg in TLB MMIO write handler, beside that
TLB vreg should update correspondingly following HW status to do
correct emulation.

When invalidating RCS TLB the device can enter RC6 state interrupting
the process, therefore the need for render forcewake for the whole
procedure.
This WA is needed for all production SKL SKUs.
v2: reworked putting and getting forcewake with help of Mika Kuoppala
v3: use I915_READ_FW and I915_WRITE_FW as we are handling forcewake on
in the code path

i915 core should only call functions and structures exposed through
intel_gvt.h. Remove internal gvt.h and i915_pvinfo.h.
Change for internal intel_gvt structure as private handler which
not requires to expose gvt internal structure for i915 core.
v2: Fix per Chris's comment
- carefully handle dev_priv->gvt assignment
- add necessary bracket for macro helper
- forward declartion struct intel_gvt
- keep free operation within same file handling alloc
v3: fix use after free and remove intel_gvt.initialized
v4: change to_gvt() to an inline

As different VM may configure different render MMIOs when executing
workload, to schedule workloads between different VM, the render MMIOs
have to be switched.
